Rails, wall rides, and such are pretty sick and can be very gnarly. Not my style, plus I'm blessed to live in an area with quality terrain to ride nearby. I'm sure that has a lot to do with it. I also know there is an urban scene around Denver. Hell, just go check the skate park after a good snow in town.
Anyway, to each it's own. If everyone liked to do the same thing that I did, I'd probably go do something else.
