There is a L   O   N   G border between Alaska and Canada, and a great deal of it is sparsely settled if at all. Wonder if there's much of a problem there? Presumably you could go across the border on foot but I can't imagine why you would want to. You'd probably starve to do death if you did't freeze first.

Last winter when I left Vancouver British Columbia, and crossed into the USA in Washington state we stopped. Homeland Security swarmed onto the train - with dogs that were straining at the leash yet - and it was worse than the movies. Unsmiling and brusque, the agents scanned our papers and after a couple of questions, handed them back without a word and went on to the next person.

I felt not so much like a criminal as a prisoner.

Between what the airlines are doing in raising the discomfort level in the seating and the meals and what you go through in crossing surface borders, they're going to get us trained to just stay home.
