The whole concept of the painted streets is still a bit foreign - and eye-opening. My experiences with organized rides include two big local rides: El Tour de Tucson and Tour of the Tucson Mountains, which are big enough to have police at intersections, and the rides put on by a couple of Tucson organizations- GABA (Greater Arizona Bicycling Association) which uses the roadside signs. When we get to the point of deciding the route, that might help us figure out if we need to paint streets.
