Montana to Nashville
Hello, We are planning a trip from Alberta Canada through Montana, South Dakota and south through Kansas City and finally to Nashville. About 30 day trip.
My question is about the highways across Montana and to some degree South Dakota (I have been through there) How are the highways from the Canadian border to Billings Montana, and then east from there to Rapid City.
I assume they are Interstates but how hilly, winding etc. We have considered an alternate route heading south through Winnipeg.
