It's a shame to discriminate whether it's black, white, religion, or anything. I'd like to know just how much polution is being released in the summer due to autos trucks rv's four wheelers and so on in the park. Also just why don't they have to pay for a guide? I believe that the summer tourist is just as destructive if not more so. So let's ban them also and make it a true wilderness! Oh no I forgot this isn't a wilderness area is it. Some people would like to have rules just to satisfy them and leave others wishing they too could enjoy a NATIONAL PARK! National Parks are for people to enjoy If rules are put in place for some it should be for all no questions ask ......If certian types of snowmobiles are allowed in becaus some think that other types aren't enviromently friendly then only certian types of autos, trucks, rv's, and four wheelers should be allowed in. Electrict or natural gas only as this is best technology only, and they should have to hire a guide. I guess some get a little confused between the difference of a National Park and a wilderness area. They both have their place. It's something for All to enjoy
