A rock climbing day features outdoor climbing walls, cliff routes, and climbing holds used by climbers.
Counted, not streamed: Rock Climbing Day has no time series, so it is read as a footprint across places. All-time count by city.
Things that happen: permits, collisions, crimes, inspections. All-time counts.
