RE: Colorado Help
Basically, the eastern plains and the western plains are like a desert, I guess. At least there is a lot of cactus and few trees. The mountains are forested with pine. The best deer hunting is arguable. There are some great deer found on the plains, BUT the plains are nearly all private lands, with a few public lands to be found. There are pockets of very good deer hunting in the mountains, along with alot of elk.
Lots of national forest that is open to public hunting!
