Denver.

Denver's older neighbourhoods are full of brick bungalows and post war homes with original hardwood under two or three later floor coverings. Pulling up carpet in one of these houses and finding a floor worth refinishing is common enough to be worth checking before anything is ordered, and it is usually the cheapest good outcome available.

The rest of the picture is the climate, which affects every house in the city equally. Denver's relative humidity is far below what wood flooring is manufactured for, so material has to acclimate in the house before it is laid. That is true on Colfax and it is true in Cherry Creek.
