You could substitute any US city for "Denver". With the spring weather I'm seeing more cyclists out. Guess what the number one complaint is: no safe place to store the bike while at work or running errands. Until some sort of bike locker is available everywhere there are handicaps parking spots, you won't see many commuters or errand riders. I would love to ride for errand, but no way I'm going to chain my bike to a post.

I've never seen road rage here. You want road rage, try a congested area like SF.
