When I was a kid, I had a pair of stilts. I believe I got them for Hanukkah, probably in 1985 or 1986, and worked my way up to the highest notch in the wood. It got boring just walking around so I taught myself some tricks, like like spinning one around, and tossing one to the ground while staying up for a minute or so without falling.
I’m not sure what happened to them – last I saw them they were in the corner of the garage, and I probably haven’t used them in more than 20 years, but I’m sure I still know how – just like riding a bike.
