Jackson, WY – A temporary plan will be drafted for snowmobiling in Yellowstone and Grand Teton National parks next winter. The National Park Service will start taking comments on the plan in mid-June and is hoping to hear new information about winter use. This comes as there are two conflicting court opinions on whether snowmobiling should be allowed in the parks. Yellowstone spokeswoman Cheryl Matthews says they want to provide the public with some certainty about next winter. She says confusion over the issue led to fewer winter visitors this past year. Matthews says they'll consider a range of options, everything from strict limitations on the marchines to not allowing any snowmobiles.
