State of Washington through northern border states to MI

There's a Towne Pump truck stop at Shelby, Mt., a rest area at Ft Belnap Reservation, MT., an unused weigh station at Malta, MT., A very large rest area at Culbertson, MT and also a town park, the Minot, MT Walmart, a park along the river in Grand Forks ND, (check this one as it floods often in the spring). Lots of rest areas along the road in MN, and once past Duluth, many more rest areas and just vacant parking areas along US2 in WI and the UP of MI.

Hope this helps.
