The Wilderness Act makes it illegal to use motorized equipment in designated Wilderness areas. The idea is so people have a place to go and have sollitude and can get away from modern noises. There are some exceptions but I don't want to get into a educational mode. I will say though that it was a hunter with extended hunting pack trips in mind who is responsible for starting the Wilderness system we have in place. That would be Aldo Leopold who got the Forest Service to set aside the Gila Wilderness we have here in New Mexico. It's now one of my favorite elk hunting spots.
