The funny thing about Colorado - I thought it was an environmentally conscious state with focus on green energy and recycling. There are more darn pickups and SUVs here than I have ever seen. The #1 selling AWD - Subaru.
I was just in the Durango area visiting my mom and doing some skiing. A truck is pretty much required, they live on a steep dirt road that was covered in snow. Also there seem to be a ton of rough roads to access hiking and backcountry stuff, you won't get out there without 4WD and some clearance.
