Having lived in Colorado for 15 years, I have a special fondness for that region - Colorado, Montana, Wyoming, Utah, New Mexico, Nevada, parts of Arizona - Flagstaff, Sedona. The only way you could handle Phoenix or Tucscon would be to summer over somewhere else. The popular Phoenix escort Don Blueyes (retired) used to do that. He stayed home in the winter servicing all the snowbirds and traveled in the summer.
