Get to know Henderson
The practical stuff — trash day, town hall, schools — plus the town’s story and where to go. Kept current by neighbors.
Fix a detail, add a fact, or just confirm something’s still right. A change goes live once two neighbors confirm it — and you earn karma for keeping the guide fresh.
Fixing a detail and confirming a fact are live today — adding facts and explainers come next. A fact’s stamp turns from green to amber as it ages, nudging a re-check. You can’t confirm your own edit.
