The list sort of surprised me.  

1. Austin, Texas
2. Denver, Colo.
3. Colorado Springs, Colo.
4. Fayetteville, Ark.
5. Des Moines, Iowa
6. Minneapolis-St. Paul, Minn.
7. San Francisco, Calif.
8. Portland, Ore.
9. Seattle, Wash.
10. Raleigh & Durham, N.C.

Despite the time I spent in Arizona I never went to Colorado Springs and never spent more than a layover in Denver some how.  I had been to the South Western corner of Colorado but somehow always ended up going around Colorado for the most part.   Love the West though.
