when I was a young teenager, between school and my neighbors used build box cart derby cars.
I never had one personally car of my own. ( my father and i build a minuate soap box debery car for cub scout race. my father really build the little car, i sand paper only on the car. we came pretty much last in the race, because one of the wheels came coming loose. my father was more disappointed than i was of the lose. i had fun spending time with my father. ) and the cars were plywood wood, with we had buy the wheels. or take off, baby strollers, those wheels really work.
the 10 speed bicycle and tricycle's wheels are pretty good to use. the body of the car was more go cart's out of wood, not the kind, you see in kid's races.
I remember in school, that we had two go carts make out of bits and pieces. they were pretty cool until our principal in elementary school didn't like we were drag races in our playground. we had a good hill to go down, we didn't have any motors on the cars. the whole thing last four days, on the school's playground.
my neighbor's friends were mechanical inline to build anything with tools. I try remember, I know we build something, I can't remember what it is. I used my red radio flyer down big hills, and radio flyer's sledge on hills. my neighbor's friend and i like to build car and ship's models. by myself, i wasn't great (pretty bad, almost pretty bad. surprisely, i never addicted by airplane glue. i had a lot of glue on my hands and the models, i was working. i never addicted.
)make models on my own, i had fun try.
i just realized that i had typical childhood with friends and neighbor's friends, that not having to be high school's classmates as friends outside the school. even today, my high school's classmates are distance to me.
