I hunt in CWD unit in Colorado. We were required to submit the heads for testing (Elk and Mule Deer). CWD has been an issue in Colorado for 20 years. The group I hunt with has been in the same unit for 25 years and not a single positive test. In the last three years (mandatory testing) we harvested 8 Elk and 14 Mule Deer. Most of the positive seem to show up in urban area where hunting is resricted or limited and people feed the animals. No baiting is allowed in Colorado. Gives you something to think about - No hunting, feeding, out of balance with mother nature and you have CWD. We no longer are required to submit the heads but there are stiil restiction on transporting animals and disposing of remains of animals from the CWD units.
