Metal is a durable material, typically appearing as reflective, machined, cast, rolled, or weathered solid surfaces.
Counted, not streamed: Metal has no time series, so it is read as a footprint across places. All-time count by city.
Things that physically exist: street furniture, signs, buildings. All-time counts.
