The stupidest thing I have ever done...
Same friend, around 1983, we decided to make a trip across the border into the U.S. one weekend, for something to do. We got to the border, myself, my best friend, another friend, and his girlfriend, in my car. It was after midnight, probably between 1 and 2 a.m. when we attempted to cross into North Dakota, and the Border patrol asked for everyone's ID. Things were pretty lax in those days, but ID was usually a driver's license or birth certificate. Turned out that buddy had left his wallet in his car, which he had lent to his sister, and she had taken it across the border for a weekend getaway herself. Border Patrol agents decided that since he did not have any ID, they were not going to allow my friend to leave the building, he couldn't go into the U.S. or return to Canada until he provided some form of identification. I volunteered to drive the hour or so south to the city where his sister was believed to be spending the weekend, and try to locate her and his car. My other friend stayed at the border, and his girlfriend came along for the ride to keep me company. We drove down to the city of Grand Forks N.D. and even managed to find his car after about an hour of searching motel parking lots. So now it's around 3 a.m. in a foreign country, and I'm breaking into my friend's car, and stealing his wallet, then driving the hour and change back to the border to pick him and my other friend up, get him through the border, and then drive back south to go and have breakfast, hang out for a few hours, and then drive the 2 plus hours home later the same day.
