To the riders who are asking about routes to the Spokane rally, I would be very disappointed if any of you choose to ride the interstate slab! If you are coming from the east or south east you need to go through Cody Wyoming, Chief Joseph highway and the bear tooth pass and Yellowstone park all in the Northwest corner of Wyoming ( South west corner of Montana). Next Central Idaho, Ketchum/Sun Valley north to Stanley, Salmon, North to Lolo pass west into the panhandle of Idaho. North to Spokane. If you want to see some country, ride twisties and have a great vacation DO NOT RIDE THE INTERSTATE. We have the best riding in the states in this area. Welcome and be safe.
