er,... Not Really. The govt. seems to have given up any effort to even appear responsible.

Washington Times: "Washington, DC, Aug. 20 (UPI) -- The Bush administration has proposed lifting the Clinton-era ban on snowmobiles in Yellowstone and Grand Teton national parks.
The National Park Service Thursday proposed letting up to 720 snowmobiles run in Yellowstone per day and 140 a day into Grand Teton for the next three years until final numbers can be established.
The move comes amid separate ongoing court challenges to the ban, one that upheld it and another allowing 950 snowmobiles a day to operate in Yellowstone.
The Bush proposal represents a compromise among the five separate plans examined by the agency to deal with the issue, which ranged from keeping the ban in place to allowing nearly 1,000 vehicles a day into Yellowstone"
