Grandstand & race night
Sprint cars Friday, the tractor pull Saturday, demolition derby Sunday. The pit gate opens at 4:00 and the stands fill by 6:30.
Pember County's four best days
Four days.The whole county.
The midway lights up Thursday and the last hog leaves the show ring Sunday night. In between: fair entries and the show ring, festival vendors and volunteers, race night and fair week operations — all run out of one little office by people who'd rather be watching the tractor pull.

01 / The grounds
Everything a county does in August.
Harvest Days is the festival and the fair at once. The grandstand runs race night, the barns run the show ring, Food Row runs on fryer oil, and the whole thing runs on neighbors with clipboards. This page is what the county sees. The Grounds Office below is what the committee sees.
The midway
Rides, games, and the ferris wheel you can see from the highway. Wristband night is Thursday.
Show ring & barns
Swine Friday morning, cattle Saturday, the round robin Sunday. Ribbons pinned by judges, not by software.
Food Row
Eight booths, one long line. Kettle corn, pork burgers, pie by the slice from the Methodist ladies.
Craft & home arts barn
Quilts, canning, photography, and the zucchini nobody can explain. Entries close the Monday before the fair.
Free stage
Polka at noon, a cover band at night, the talent show Saturday. Bring a lawn chair; leave the good one home.

03 / The workflow
The Grounds Office.
The poster on every phone pole opens into a control room. Three desks the committee actually works from during fair week: vendors, volunteers, and entries. The AI reads, sorts, and drafts. A committee member signs off before anything leaves the office.
Demo data — nothing here is realEvery desk follows the same rule: intake comes in, the repeatable part gets done by the machine, and a person you could find at the beer tent approves the send. Nothing mails, texts, or posts without a name on it.

Review
Volunteer shift grid
Gates, parking, the beer tent, and cleanup across all four days — plus Sunday teardown, the shift nobody signs up for. 31 signup sheets are in the pile. The desk schedules them, flags the holes, and drafts the reminder texts. A person reviews every text before it goes.

Nothing scheduled yet — the signups are still a paper pile.
Judging sheet & payouts
Placings entered by the judges' clerks. Premiums total from the book — so the checks add up the first time, and the treasurer goes home Sunday night.

The human gate
Acceptance letters, reminder texts, and premium checks all pause at a committee member. Nothing sends without sign-off.
AI may
Read applications, spot missing documents, propose booths, schedule shifts, draft texts, and match entries to the premium book.
AI may not
Accept a vendor, promise a booth, text a volunteer, or cut a check. It drafts; people decide.
Data boundary
Everything on this page is invented and stays in your browser. Nothing is uploaded, sent, or stored anywhere else.
04 / How this demo works
Honest about the machine.
The Grounds Office is a working demonstration, not a screenshot. The AI steps read what you type — the vendor desk really parses your application, the shift desk really schedules from a signup list, the entry desk really matches the premium book. In production these same steps run through a small language model behind DID's demo backend; here, rule-based versions answer so the page works anywhere, offline, with no keys.
What stays with a person: every acceptance, every text, every check. The committee member is the last step on purpose. And to be plain about it — every vendor, volunteer, exhibitor, and dollar figure on this page is fictional.
