Probably even better if there is ice and snow and you slide all the way! Oh, wait, the rangers close the road if there is any snow, ice, high winds!I can beat that. I will post the picture if I can find it. I went from the Newfound Gap overlook in the Smoky Mountains to Gatlinburg. I think it was over 100 mpg. I donāt know if I hit the gas once on the way down.
