Howdy All,
First!¡ The park system was NOT set up as a Wilderness. That is another designation. They were set up so people could go to them and enjoy and preserve them. There are Wilderness areas in the parks where no machines are allowed.
Next!¡ We have NOT been losing Wilderness areas. We have been gaining them.In fact there have been areas that have been designated Wilderness study areas (WSA) with man made objects in them.
I'm still trying to figure out how you destroy snow
As far as taxing snowmobiles to pay for grooming trails. That is what the entrance fee is for. They don't tax hikers, horseback riders, fisherman and other visiters so they can maintain all the facilities at the park. There have been some thoughts of user fees.
