How about "shagging" [grabbing on to a vehicles bumper in the snow and going for a nice little free ride] ?
We were constantly doing that, hours and even whole days at a time, into the night. After school we would get a cute little girl [accomplice] to wave down a car and ask what time it is ,, While the guy was gladly obliging, half a dozen of us would latch on to the bumper, so much so that sometimes the car couldn't even get moving, and a few would have to drop off.
It was somewhat of a sport and I was known as one of the riskiest. One time a Ram truck was waiting for a train to pass so me and my buddy latched on to his bumper for a free ride to the store we were going to. guess he got tired of waiting and decided to back up, my buddy hopped out of the way in time but all I could do was just lay down and hope he didn't run over me, I can still remember looking up and seeing that transmission spinning inches over my head, he cut the tires and just missed me.
Other hazards were sewer lids, if you didn't see them coming in time you were in for a rough ride, you'd go skidding for 10-25 yards depending on how fast the vehicle was going ... Railroad tracks would also ruin your day, but we generally knew where those were at and were rarely surprised by them. Don't see kids doing that anymore and I guess its for the best, easy to see the danger now but seemed like a great idea at the time.
Train hopping too, I was a massive train hopper, sometimes going across the state then hopping a train back. I'd hop fast ones, slow ones, was thrown from more than one that were going too fast and I lost my grip. That stopped when a guy I knew, not really a friend, got his leg cut clean off hopping trains. I asked him about it later, he said it didn't hurt at all, and he thought it was just a nightmare and not really happening. Luckily he survived, got a fake leg and walked so good you'd never know he only had 1 leg.
