This past winter, we spent a day in Yellowstone National Park with the Department of the Interior to kick off the America 250 celebration, and mark a milestone: ProStar S4-powered Polaris Snowmobiles are now certified for Yellowstone and Grand Teton National Park! Experiencing these places in the winter is incredible, and we’re proud to have that ride be Polaris. usinterior #PolarisSnow #Snowmobiles #Snow #YellowstoneNationalPark
