I used to race slot cars at a big track in Vancouver just across the bridge from Richmond where I grew up. Get a clear body car and paint it up from the inside. Build the frame and buy different motors, tires etc. The place had a track with a dozen lanes and you paid for track time. Organized races with car parts for prizes beauty contests for your cars. I did pretty good in both categories and pissed off some of the older guys as I was one of the younger ones. Spent most of my allowance and paper route money on that stuff.
Then I got a Yamaha 80 and sold all that stuff to buy knobby tires and stuff to play with that instead. I put the street tires and turn signals back on it when I turned 16 to go take my driver's test on it. That lead to a couple other bikes then a year old Triumph Bonneville in grade 11 which lead to dropping out of school and lots more fun.
I'm such a dinosaur that one of the jobs I had as a young teenager was setting up pins at the local bowling alley.
