Colorado has a "walk-in" program that has opened a lot of private lands to the public for upland hunting. The DOW has maps available that show where all the lands are located and what game you can expect to find on each parcel. Our pheasant and quail numbers are as good as our neighbors to the east, but there are birds to be hunted. Unfortunately for you, you will have to buy a non-res. license since you have to have lived here several months to be concidered a resident.
