I'm bummed to have missed the signup window!
Cranky, I'm in the Denver suburbs, but I have been very impressed with the biking infrastructure here. One key is that there are tons of bike/pedestrian trails that aren't on streets, including tunnels under most major roads. So if you're looking for infrastructure on the street (i.e. bike lanes), you're missing the best stuff. I can ride 15 miles to downtown Denver, primarily along the river, only crossing a handful of streets the whole way.
Admittedly, that doesn't help you get from place to place downtown, which I can't comment on.
