A couple years ago we had about a foot of snow that was covered by about an inch of ice due to raining and re-freezing. We went out to my buddy's parent's place, they have a 12 acre field on a hill, and had the quads out plus just about anything else we could find that would slide on the ice. Ended up running my warrior into the split rail fence at the bottom of the hill a few times and trashed the bumper, and then Brandon slid his Dukes of Hazzard orange Ford Ranger clean through the fence, across the road, and about 40 feet into the neighbor's yard because the truck was just floating on the surface, that's some thick ice. The real mistake I made though was when I got my street luge out though, I probably had it up to about 60 miles an hour before I realized I had no steering, no way to stop, and a slower sledder was directly in front of me. I bailed off the luge, crashed into him which knocked him off his sled (truck tailgate) and we both ended up in the road by the time we actually stopped sliding. The real terrifying thing was when I turned around to see a truck tailgate coming towards my head at about 20 miles an hour, that was the quickest I ever jumped up and ran on ice. That truck tailgate hasn't latched right ever since that crash haha.
Took the door off my mom's clothes dryer once and used that as a sled when I was younger, the ass whoopin taught me to never do that again. Still not as bad as when my uncle popped a fender skirt off of my grandmother's 55 t-bird when he was 12 and used that as a sled, tore it all to hell. I think he was still feeling that ass beating 20 years later. To this day the man won't go near a sled.
