You could be right Szihn. I have killed antelope in New Mexico and Wyoming, and though stronger,they were ok ,but were in that short grass prairie. Anything I have killed in Colorado that were remotely connected to sage brush were terrible.I even quit hunting them for awhile because I could not get them past my nose. When I finally got permission to hunt an bunch of land in eastern Colorado, there was a remarkable difference. I am no neophyte in taking care of wild game either.
