Where to go for a month?
NORTH!!!!
Options:
1. Alaska (via both the Alaska Highway and the Inland Passage (marine highway).
2. The Yukon & NW Territories
4. Hudson's Bay region
5. Nova Scotia
6. Labrador/Newfoundland (did NF in my car about 30 years ago...think it would be a grand adventure to take the TM over there on the ocean going ferries for a couple of weeks) .
7. Prince Edward Isle (another Canadian province, eh

...one of the few I haven't yet been to! ).
8. North shore of Lake Superior, Quetico park, Boundary Waters Canoe Area.
9. Northern Manitoba and Saskatchewan...as far as the roads will go.
10. And for shorter trips, the Glacier/Waterton Lakes International Parks region, and Banff/Jasper National Parks. At the border between Jasper & Banff, the Columbia Ice Field comes just about down to the highway. About 20 years ago, I traveled
on my motorcycle down the YellowKnife Highway from Prince Rupert BC (on the Inland Passage just south of the border with Alaska) through Jasper/Banff/Waterton Lakes/Glacier/Yellowstone/Teton parks. Great adventure doing motorcycle camping but would be just as about as much adventure (and a heckuva lot more comfortable) doing it with my TM and truck.
