At Yellowstone Arctic Cat Yamaha, we are concerned about the environmental impact of motorized vehicles in Yellowstone National Park. Therefore, we have led the way in preserving and protecting Yellowstone with the most environmentally friendly transportation methods available. Back as far as 2000, we worked closely with Arctic Cat to be the first to use 4-stroke snowmobiles. We continue to work with manufacturers in developing and supporting 4-stroke technology. We also are dedicated to using environmentally friendly fuels in snowmobiles and snowcoaches. We continue to be authorized Park Concessionaires, approved to guide tours into the Park. We also contribute a percentage of our revenue to Yellowstone National Park for building and maintenance of physical facilities.
