I see Yellowstone will open from the Montana side June 1st. Some construction from West YS up to Bozeman. The NE corner of the northern loop is closed. This is the only section I have not been through. On your trip planning out of Hamilton, see my ride report on the Big Hole and the Pioneer Mountain Scenic Byway. Also, as you probably know, south out of Hamilton on 93 is very nice right now with fresh pavement. Not sure if you have ever traveled through Dubois, ID and then east over to Island Park and on to the West Entrance. The unique part of this route is passing through the Saitn Anthony Sand Dunes. Not spectacular, but unique in ID. It is a nice time to ride. Getting warmer here with highs near 80. Not as hot as your side of the state.
