Roy,
I'm already cogitating about a route next summer following STAR that would take me through all of the eastern Canadian provinces. That would be pretty straightforward, but I also want to include a few noteworthy areas such as going to Radison, Quebec, Goosebay, Labrador, and Cape Spear, Newfoundland.
Visiting each of the provinces from Quebec eastward would complete my visits to every U.S. state and every Canadian province and territory in North America.
