The whitetail population is starting to extend as far west as I-25, at the base of the foothills. There is a couple of good sized herds of whiteys south of Colorado Springs, along Fountain Creek. I have seen two really nice bucks in this area. There is some good public land to hunt whitey's in CO. The South Republican SWA and Tamarack Ranch SWA are good. Getting a tag for a unit with good amounts of public land is pretty hard though. Anywhere from 3 to 13 preferance points for a late rifle tag.
