Cheyenne, WY – Wyoming is once again going to try and open up the snowmobile case. Jay Jerde of the Attorney Generals office has filed a motion with US District Judge Clarence Brimmer to try and re-open the case and return snowmobile numbers to either previous levels in Yellowstone and Grand Teton National Parks, or at least revert to the rules published by the Bush administration in December. State Trails Coordinator Kim Raap says they want Judge Brimmer to rule on a case Wyoming filed in 2000. Jerde admitted to a legislative committee that it would be unusual for Brimmer to side with the state, but he thinks they have a good case. He's hoping a decision will be made in a couple of weeks.
