The permit is for the Quad
The permit is for the person that purchases it not the machine. If you want to ride your quad one day and a dirtbike the next day, only one permit is necessary.
I will have your 3-7 day permits waiting on you when you arrive. I am an authorized vendor to sell Hatfield~McCoy merchandise. Most lodge owners are authorized to sell permits. It just makes it nicer for the people. They don't have to find a 7-11 to get one.
