I drove to Calgary from Mt. Rushmore last summer coming north on US 85 to I-94 where we stopped at the Teddy Roosevelt NP. There is a very nice RV park in Medora and dry camping in the NP. The park is worth a couple of days. We then followed I-94 into Montana where we drove north at Forrest Park on 200S and 13 to US-2. These were good roads with little traffic. We then followed US-2 over to Browning. This was a nice quiet drive with nice RV parks in Glasgow, Havre and Cut Bank. We spent one night at a city park in Shelby before we went into Canada. This year we are planning on coming east from Seattle on US-2.
