Western Montana to Harrisburg, PA (Late Oct 16) Suggestions?
We're spending the summer in Bigfork, MT (beautiful). The park closes on Oct 15th and we're heading to Fort Indiantown Gap (near Harrisburg), PA where I have an Army exercise. We're pondering whether to a) take a northern route, turning south over Michigan's Mackinac Bridge or b) head south from Montana, turning east around Salt Lake City. Concerned about likely weather phenomena (have to be there by Nov 2d), places to stay (are campgrounds open?), suggested things to see, etc.
Any help appreciated. We're a Berkshire 390RB (40'), towing a CR-v ona dolly.
