5 of us are riding Island Park on the 22nd of January and would like to ride somewhere between Driggs and Alpine on the 23rd as we will be heading back that way to Casper via Jackson. Any recommendations? If we are going to pay for an ID tag we may as well use it another day on the ID side of the pass. Am I also correct that we can't trailer over Teton Pass or does that only apply to semis?
