Most of the towns in northern Colorado are fantastic for bicycling. I've moved around a lot, and this is the best place that I have ever lived for bicyclists. You can't drive anywhere in town without seeing at least a few bicyclists tooling around town, even late at night. There will always be friction with some people and drivers, but it keeps getting better and better here as bicycling is seen more often as a form of transportation, and not just a recreational activity.
