I've seen a few on here. I lived in Cheyenne while I was in the AF and hated it while I was there. Now I miss it terribly. Go figure. The riding should be really great out there in the summer months. For the dirt, I'd go to Vedawoo(sp?). A good place to run into some cyclists would be on the century to Wheatridge and back if they still do it. Eat up all that good riding in Colorado too if you can do a trip to Rocky Mountain National or Estes Park.
