The Ural guys are riding Saturday, Jan. 5 only. Since it's such a long ride for me to get there (I'll be trailering, 110 miles) I was thinking about arriving late the day before or staying over the night after. So the 4th & 5th or the 5th & 6th. Try and get 2 days of riding in. Contacted the BTB Ranger Station to see if any of the cabins were available. Someone has reserved/rented all of them for the entire Winter.
But all 3 "dry shelters" are available. No running water but they do have a woodstove in them:
Looking specifically at Shelter #3 because it is the closest walk to the rest rooms. There really are no flush toilets in the Shelters according to the Ranger office.
You HAVE to take 2 days.
Here's a short video someone posted regarding the Shelters. They look pretty nice. Each is supposed to be for six (6) people.
