I really don't care how loud bikes or sleds are. What is disturbing, is that there are hundreds of thousands cars/trucks/motorhomes/motorcycles that travel through the park every summer. The liberals don't have any problems with that. But you cut the number of motorized vehicles that go through the park in the winter easily in half (probably more) and they think they have to put up every restriction as possible to eleminate snowmobiles. So lets see, you have more then double the amount of motorized vehicles which is double the so called polution compared to winter travel, yet they want to say that snowmobiles are poluting the park. It's such hypocritical bull sh**! If you want to enjoy the park cross country skiing or on snow shoes fine. If I want to enjoy the park on a snowmobile, that's my right as well. We each should have our right to enjoy nature the way we choose as long as we're not destroying the environment. They think they can dictate how we enjoy the park. I hate those liberal vermin! I think that's what the original authur was trying to say is how hypocritical it is that there can be loud bikes, but not snowmobiles.
