Name one thing...
I swam across the Niagara River a few miles above the falls. I was greeted by an O.P.P. officer who said if I stepped on dry land, he'd arrest me because I wasn't allowed to enter Canada at that point. My cousin was nearby in his boat, so I swam to it and we headed back to the U.S. side of the river. The officer saw us off with a wave and a smile.
