Forgot this one...
This past summer while driving from Seattle to Alaska by way of British Columbia, we crossed into Alaska at Hyder. Hyder is in the extreme southern leg of Alaska and as far as I know, there is only one road in, and that is through British Columbia. When leaving Hyder in a car with Washington State plates, at the border we were stopped for questioning by the Canadian customs/immigration! ??? Perhaps being 100's of miles from anywhere makes the Canadian government suspect everyone is trying to sneak in at this border crossing.
