Agree,
@x_files. I used to live in Maine and the border there with Canada is incredibly porous... it is very easy to walk across in the cover of dense forest (or night). Just don't get shot by a moose hunter this time of year, would be my advise! All that said, Canada is a
wicked country in winter, starting next month in some areas, like much of the northern U.S. If BL is heading to Canada (or is there), it would have to be a jumping off place to somewhere else because "winter is coming", or he has shelter.
In fact, IMO, BL, or whomever might be helping him hide,
likely planned to get BL to a location hospitable in both summer and winter... a temperate climate with dense forest, rivers, dry climate, and periodic access to provisions. Otherwise he'd have a massive backpack to survive in very cold temperatures and have enough sustenance.
Where might such a place be... not too hot, not too cold for a long period of time...? (I voted for 'somewhere else in the U.S.' for this reason).
