I'm a Colorado native and still live here despite a huge boom in the price of housing and overcrowding in recent years (damn marijuana laws. . .).
The video game/collecting scene has always been good here, especially compared to places on the east coast which I here is mostly terrible. We have a ton of retro game store, pawn shops, thrifts (most suck though), but sadly only one flea market that is 90% resellers. Regardless I do pretty well in finding stuff, although like everywhere else the pickings have become more slim in the past few years due to the sharp rise in collecting/reselling.
