I believe the proposed rules are a good effort at a responding to the needs of the park and visitors. I have been snowmobiling in Yellowstone for 19 years. Originally we seldemoned encountered the the snow coaches. In recent years they have become a real problem. I sincerely believe a smaller limit needs to be placed on snow coaches. The casue the most damage and stress the wildlife. The snow coaches create large ruts that cause the snowmobiles problems. The snow coaches seem to polute and stink more than the snowmobiles. I hope the rules will be approved with some more limits on the snow coaches.
