How about stiltz? I remember after learning to walk on them, I had to make a pair that was about 8 feet high. I used to get on my roof to mount them. I could step over my gate....LOL
Strap on roller skates with the steel wheels. Homemade wooden carts that you pushed down the hill.
Hell, I just wish I could get my kids out from behind the computer long enough to go out and play hide and go seek!!!! Kids now days don't even want to go out and play. When I was a kid, I left home to play in the woods after the sun came up, and didn't go back indoors until the street light came on. Yeah, my dad was one of those that said I better have my a** in the house before it came on or else. So, as a kid, you learned the sound of the street lights. You know, the buzzing sound they make when they are trying to come on. By the time I ran home, that light was just about to pop on bright!... There were a couple times I didn't make it and had to suffer the consequences. And yes, that's back when corporal punishment was handed out by every father of every family I knew....
