Wow, first off I'd like to apologize for the rude comments made earlier. Yes, Colorado had been hit VERY, VERY, VERY hard by the recent drought. Ranchers have been selling off their stock at extreme discounts and some of the smaller ones have been unable to pay off property taxes and therefore are having to sell the ranch. The scene has been changing annually out here both in who owns the land, and where the animals are going. Since crops haven't been doing well at all, the animals are going to very different behavioral routes.
Second, there are some great opportunities to hunt white tails out here, if you do the legwork. The units along the major rivers are always good producers, year after year. There are also some good SWA's along some of the major rivers that hold good whitey's. That being said, any unit with SWA access is a high point unit. Some of the best areas for white tail are out in the plains. The unit I hunt doesn't have a single running creek within 45 miles of any of the boundaries, but we kill 150+ bucks every year.
I know this is the long winded way of saying. get out and do the legwork, but some awesome opportunities can be found here. If I was you i'd save points, head to one of the higher preference point units and knock on doors while your out there to find a rancher that'll let you whack a whitey in a 0 preference point unit.
