I  remember in the early 90's at Thunder Mountain, someone knew that "Genesee" John Hoffmier ALWAYS had a cooler full of ice cold Genny in the back of his pickup. So for 2 weeks in a row, someone would take his cooler and beer. So the third week we saved up 12 empty bottles of Genny and filled them up with pee, put them in a styrafoam cooler, covered them up with ice and left them in the back of the truck. Just as we expected, someone took the cooler. They never did it again. I personally thought they wouldn't be able to tell the difference.
