Not sure how you would do it and not be a snowbird, Ches. Out here on the Wet Coast we get lots of Inlanders fleeing the snow and ice, but it's still only 5C and raining all winter, so it's not exactly full-timing weather. Even something as lush as one of Reace's chariots would get a little cosy after four months of full-timing in the rain.
I think, realistically, a lot of the deep winter months would have to be spent in the U.S. — mid November to mid April — then back to B.C. for the shoulder seasons and wherever in this great land for the summer. It's a goal we've set as well, and I can't really see a way to stay north of the border and full time — not in any real comfort, anyway.
But there's lots smarter people than me out there, and perhaps one of them will offer better advice than I can.
