Hey buddy welcome to Colorado. There is lots of public land across the state. Look for the wilderness areas on a map they are good places to start. What part of the state do you live in and i can give you a better idea of where to look.

I just glanced up and realized that you were talking about antelope i presume. Sorry I got Deer and Elk on the brain! Disregard what i said about the wilderness areas. Yes you are right there is alot of private land when it comes to pronghorn hunting. That is why it is so hard to draw a decent tag in this state. Some areas that you have to draw for rifle you can hunt archery.
