As a Born and Raised Arizonan, I can tell you the rides are mostly "Climbs" in that neck of the woods. People really get into the bike rock climbing thing, often nearing the cliffs or outskirts of Rye, sometimes grand canyon area if the weather provides [a place it DOES see snow].. I would say your two best best are,
A. Going to Tuscon, 4th Avenue is all about bikes and arts and independent smoke shops. There are a number of custom bikes out that way, and even several bike oriented shops to be had on 4th. [maybe its 6th? either way its like side by side streets].. these are the kind of people who would have a regular ride, or annual. Very cool location, very flat.. cool people..cool scene..
your other option being B. Create your own chapter, and begin to organize it. Make a FB for it, others can follow and coordinate plans.. flyers for the bulletin boards in super markets, even here! Im currently residing in Rhode Island with my Girlfriend, but I could spread the word to some of the folks I know there and we could really make a thing of it!
Im here daily, so discussion comes freely.
Id be happy to hear what you think, with this said. Maybe I can figure out a few other options, as a two way ultimatum does make for a dry feeling, and not just the desert.
