I just got back from 10 days at the Algonquin Provincial Park in Ontario. To my Canadian friends, it was the most fun I have had in a long time. Beautiful area. I have not crossed the border in years. I was actually a little nervous going over even though I had nothing to hide. And when the border agent asked me what my tag number was I drew a complete blank and instead of retrieving the registration card I asked if I could get out and look at it! And I gave her more forms of identification than she needed or wanted! Coming back it was smoother even as I had quite a few purchases I would have declared if asked. Yes, engage the agents in direct response to their questions. As a law enforcement officer I would have felt odd being searched but of course we know the world has changed and the protocols now in place are a necessary evil.
