the delema is how do you balance the park’s mandates of preserving park recources. should they ban snowmobiles from the park and only allow people to travel by snow coach ,skis,or snow shoes only. I think that they want to ban snow mobiles beacuse they make too much pollution.Here are some pros and cons for this.pros,driving a snow coach is better than walking , snow shoes don’t sink in snow. cons,on skis you could get really hurt,snow coach cause pollution, snow shoes don,t get grip on ice.I chose those pros and cons to show how the ways to travel are good and not good.i think that driving a snow coach would be better than walking beacuse you can get to your destination faster. I think that snow coaches are also bad beacuse they make pollution.I think that snow shoes are good beacuse they do not sink in the snow.
