Just an update that this is progressing, although at the speed of gov't.
Border to Border Touring Route - Minnesota DNR
Most of it could be done now on County and Forest Roads but there are some sections of the proposed route that are currently hiking and snowmobile/ATV trails only.
Lake of the Woods County was one of the primary issues from what I have heard and it mentions they are reviewing the latest proposed route. Otherwise, it will just bypass that county from what I understand.
I'm certainly looking forward to running it upon completion of the route and as you guys mentioned, connecting it with the TWAT as well.
