I lived in Cheyenne for awhile. I would say if your looking for change, you will like Casper. Not much in the way of civilization between the cities. The wind seems like it is always blowing in much of the state which can wear on you. The altitude will take some getting use to....you may feel like your out of breath when doing anything strenuous for awhile until you adjust. It is a semi-arid climate so you may like not having humid summers, but stock up on chap stick until your body adjust to the new climate as your lips will be the first thing effected.
