I'm thinking of doing 2 bike trips this year; Colorado and Wyoming.

I've biked Colorado (Crested Butte, Fruita) but never had the opportunity to try Wyoming.

Are there any good, technical and fun areas in Wyoming to ride?

Just Googling around, there seems to be 5 areas (Jackson, Rock Springs, Casper, Cheyenne, Sheridan) that show promise.

Suggestions?
