Back in the 70's when "Vanning" and van clubs were the rage, we attended the Midwest Truck-in in Monticello, Indiana one year. It was crowded as all hell, with barely enough room to park your trucks. Well, it rained one afternoon, and it was getting muddy. One guy, "Budweiser" was his handle, brought a bean bag chair, and it eventually sprung a leak and began discharging little white styrofoam balls everywhere, and were getting tracked everywhere too. People had enough, so a couple of us took about a gallon of these styrofoam balls and poured them down the defroster duct in his van, turned the blower to HIGH, and set it to defrost, and cleaned up any evidence. This being the middle of summer, everyone was sweating like crazy, and someone told Budweiser that he had to move his van a little farther from the fire pit. He gets in, turns the key and WHOOOOOSH! instant snow storm! He gets out of his van looking something like Frosty the Snowman, just covered in styrofoam balls head-to-toe. We were all laughing so hard it hurt.
