If the conversations I had with visiting Canadian cyclists this week were any indication, they view Tucson as a fantastic place to visit for spring cycling. I ran into a couple and also a big group of cyclists from Montreal, as well as a couple from western Canada. That was up at Saguaro National Park, one of the most scenic locations for road cycling around Tucson.

And I have encountered a number of visitors from Sonora, Mexico, who were here for road cycling or mountain biking and were enthusiastic.

As far as urban/commuting etc, i don't know people feel, although Tucson does have extensive bicycle lanes for getting around.

On the other hand, the new "modern street car" project, still under construction, is extremely non-friendly to cyclists, with some dangerous tracks and almost impossibly narrow sections of pavement....
