Thank you for your info, My Dad lives in Colorado and has hunted for years, however do to his back he has not hunted in 20 years. he is now 68, From what research I have found from Co. the ATV deal you can use them , however you have to stay on trails etc. and can use them to get your animal out. As for base camp, how far can a person get say gunnison area or the flat tops?? Once again thanks for you help and input..
