You are correct in not wanting to go over Teton pass with the MH. 10% grade for about 5 miles each side. Outstanding ride on the M-cycles though. Be sure to stop at the top of the 8432’ pass (cool the bikes) and look at the lower section of Jackson Hole. The Gros Ventre Butte prevents the view of the town of Jackson though.
Highway 31 to Swan Valley does go over a small pass but a piece of cake for the MH.
At the junction of 31 and 26 in Swan Valley on your left is the Rainey Creek Mercantile, go in and get a SQUARE hand dipped ice cream cone, ask how they came with square ice cream dippers. Obviously square dipped ice cream tastes better!
As we live about 50 miles from Swan Valley, PM me if you want additional information.
