Colorado, I need Help

Ok, here is the deal. My wife has finally agreed to move to Colorado. We are big into the outdoors. Hunting, fishing, skiing, and definitely riding. We need to be within 1-1.5 hours of Denver airport. Here in Tennessee I have tags on all of our UTVs and we drive them all over town. Where would be a good area to start looking? I am very concerned with the liberal movement and that may just keep us in TN.
