It is Thursday, June 4, at roughly 10 AM. Acalanes graduates tomorrow — Friday, June 5, on the football field, 6 PM call time, gates open at 5. Campolindo graduates Saturday. Miramonte rolls out a week later. The lawn signs went up two weeks ago. The parties were rehearsed in the driveway last Thursday by some other family practicing for some other weekend. Today is different.
Today the supply chain shows its face.
If you drive Mt. Diablo Boulevard between Pleasant Hill Road and Oak Hill at 10 AM today, you will see them. Vans. Tents. A truck of folding chairs in white. A florist double-parked with the hazards on. A young woman in a blue apron carrying three trays of cookies vertically. The graduates are still in finals. The parents are at work, pretending to focus. The vendors are the ones living this week.
Allow me to introduce you to them.
The Caterer
There are roughly six caterers who do the bulk of Lamorinda graduation parties, and right now all six of them are operating at 110% capacity. The Lafayette Park Hotel’s catering kitchen is doing three rehearsal dinners tonight. Casa Orinda is at a soft full. Postino, Batch & Brine, Metro Lafayette — they all have an off-site team somewhere in town today, prepping a buffet for sixty in a backyard with insufficient counter space.
The caterer’s Thursday is the worst day. Friday is the show. Saturday is the bigger show. But Thursday is when the count changes. Three more relatives flew in. Can we add a vegan option. My nephew is gluten-free now since April. The cousins are bringing their kids — we said no kids but now there are six. The caterer says yes to all of it, charges a small change-order fee, and goes back to the kitchen to butterfly more chicken.
If you are driving behind a refrigerated van today and it is going twelve miles an hour because the driver is squinting at house numbers on Reliez Valley Road, do not honk. That van is carrying a salmon platter that costs more than your rent.
The Florist
There are two florists in downtown Lafayette who do this for a living and one is doing it from a converted garage. The “graduation flowers” market is a specifically Lamorinda phenomenon: a bouquet of long-stemmed roses, given to the graduate at the ceremony, photographed approximately 800 times. Then a second arrangement — bigger — for the party. Then a third — smaller, simpler — for the rehearsal dinner. Then, sometimes, a “leaving for college” flower for August.
The florist has been working since 5 AM. The roses came in from the Bay Area flower mart at 4. The greenery is being conditioned in buckets in the back. The graduation lei orders — yes, this is a thing now, a Hawaiian custom that made the jump to mainland Lamorinda about ten years ago and now nobody questions it — are being assembled at a card table by a high schooler the florist hires every June.
The florist will sleep four hours tonight. She will not eat lunch tomorrow. By Saturday at 9 PM she will be sitting in her own kitchen with a glass of wine and a frozen pizza, and she will not look at a rose for two weeks.
The Party Rental Company
If you have not been to the Bayside Rentals lot in Concord on a Thursday in June, you have not seen anything. Eight trucks loading simultaneously. Stacks of white folding chairs being counted out — 148 for Reliez Road, 96 for Glorietta, 240 for Moraga Way. Folding tables. Linens. The big rectangular Cambro hot boxes. The infrared patio heaters that nobody needs in June but everybody rents because “what if it gets chilly after sundown.”
The bounce house economy is a separate sub-industry. Acalanes graduations have officially aged out of bounce houses but plenty of Campolindo and Miramonte parties this weekend will include a younger sibling’s whole friend group, and a bounce house is still the cheapest way to occupy fifteen 8-year-olds for four hours. Three local companies. All sold out for Saturday since April. There is a waiting list for bounce houses.
The rental company driver who delivers your white folding chairs at 11 AM tomorrow will deliver another order at 1, and another at 3, and another at 5, and he will be back at 7 AM Sunday to pick them all up. He has been doing this for nine years. He knows your driveway slope better than you do. Tip him.
The Photographer
Every Lamorinda graduation photographer has been double-booked since March. There is the ceremony package — they shoot the field at 6 PM, deliver gallery by Monday. There is the party package — they shoot the home portrait, the cake cutting, the speeches, the inevitable group shot of dads-on-the-porch-with-bourbon. And there is the family portrait — the one that’s going on the holiday card, that includes the dog, that takes 40 minutes because the cousin’s toddler is having a moment.
A good Lamorinda graduation photographer does three families on Saturday. Charges between $1,200 and $2,800 per family. Edits all next week, delivers by June 18. By July they are shooting senior portraits for the next class of seniors, because the cycle does not stop. The cycle never stops.
The Cake
Susie Cakes in downtown Lafayette has roughly forty graduation cakes coming out of the kitchen between Friday morning and Saturday night. Forty. Each one personalized with the graduate’s name in piped icing, the school colors, sometimes the college mascot, sometimes a tiny fondant diploma that looks slightly tragic.
There are also the home bakers. Every Lamorinda neighborhood has at least one person who “does cakes on the side” and is, in her own way, a small business that has been quietly compounding for fifteen years. She has nine orders this weekend. She is in her kitchen right now. There is fondant on the dog.
The Helium Crisis
This is its own phenomenon. Every June, sometime around the first week, the helium tank rental at Party City in Walnut Creek runs out. Not low. Out. The graduation balloon arch industry — yes, that’s an industry now, a freelance-mom side-hustle, $400 for a full driveway arch — is hoarding tanks like preppers. If you wait until Thursday morning to source helium for Friday’s party you are too late. The mylar “Class of 2026” balloons are still available but you’ll be inflating them with your mouth.
There are forty-two graduation balloon arches going up in Lafayette alone this weekend. I am not exaggerating. Drive Glorietta Boulevard on Saturday morning and count.
The Taco Truck Block
The party catering arms race ended around 2019 with a clear winner: the taco truck. Cheaper per head than a full caterer, beloved by every age group, requires no plates, occupies the driveway for exactly the window you need it. Three Lamorinda-area taco trucks are booked solid this weekend. Solid. If you tried to book one yesterday for Saturday you got laughed off the phone politely.
The taco truck people are the unsung heroes of Lamorinda graduation season. They show up at 4. They serve 80 people in 90 minutes. They pack up at 7. They drive to the next party. They are home by midnight. They sleep five hours. They do it again Sunday for a quinceañera in Pittsburg.
The Lafayette Park Hotel Rehearsal Dinner
Tonight, by 6:30 PM, the Lafayette Park Hotel & Spa will have four rehearsal dinners going. The Park Bistro & Bar has been booked for graduation-related private dining since the spring. The terrace seats 40, books at 6, turns at 8:30 for a second seating, books another 40, and somehow the staff makes it look easy.
The hotel itself has out-of-town relatives stacked three-deep. The Costco-sized parking lot will, by 5:45 PM, look like an East Bay luxury car dealership. Tesla S, Tesla X, Tesla 3, Audi Q7, Audi Q5, the occasional G-Wagen from someone’s brother-in-law from Atherton. The valet stand is staffed up.
The Friday Morning Traffic Note
A practical word: tomorrow, Friday June 5, between 5 PM and 6 PM, Pleasant Hill Road in front of Acalanes High School will be unpassable. Gates open at 5. Ceremony starts at 6. Approximately 1,400 family members and friends are converging on a single high school football field. If you have any errand on Pleasant Hill Road between Stanley Boulevard and the freeway between 4:30 and 5:30 PM tomorrow — abandon it. Reroute via Mt. Diablo Boulevard. You will not regret this.
Saturday Campolindo does the same thing to Moraga Road and Camino Pablo. Plan accordingly.
The Quiet Truth
Behind every lawn sign is a vendor working a sixteen-hour shift. Behind every “We Did It!” balloon arch is a freelance mom who has been on her feet since 6 AM. Behind every salmon platter is a refrigerated van crawling Reliez Valley Road. Behind every diploma cake is a baker who has been awake since 4.
The graduates do not know any of this. They are at home, in pajamas, scrolling, vaguely aware that something is “happening tomorrow.” They will walk across the field in a slightly-too-large gown, hug their friends, take 800 photos, and have the best weekend of their lives so far.
That is exactly how it should be. The supply chain is invisible on purpose.
To the caterers, the florists, the rental crews, the photographers, the bakers, the balloon arch moms, the taco truck operators, the Lafayette Park Hotel banquet staff, and the one florist’s high schooler making leis at a card table: thank you. The class of 2026 has no idea what you’ve been doing for the last six weeks.
The rest of us see you. We see the van going twelve miles an hour on Reliez Valley Road. We see the truck of folding chairs at 7 AM. We see the helium tank in the back of the Honda Odyssey.
We see you. Tip well.
