A new facility has opened very near to the GDMBR that would be of interest to those touring the route. Likely not so much racers of the TD, unless an emergency resource is needed.
Whitefish Bike Retreat just opened its doors this week. A bike based hostel with camping and bunk rooms - and a limited number of private rooms. Cricket Butler is the owner, an Ultra rider/racer and general adventurer and bad-ass.
She's offering shuttles as well as lodging. Could prove a great resource.
