Just to bookend the passport story, it should be noted that no one made any comments about my passport on the way back in. When I got to the customs person, I dropped the passport on his counter and said “It’s been washed” before he could do the dead fish routine. He just laughed, stamped my customs form and said “welcome back!”
So, ain’t nothin’ all bad. Not even customs.
Wow, so the Canadian customs agents were uptight and the US customs agents were laid back. That’s the opposite of what I’d expect.
