When I was a kid in the early 90s we used to just make our own dangerous fun. One particular thing we liked to do was ride cardboard boxes down the exposed-wood exterior stairs at the apartments I lived in. Or if inside, mattresses down the interior stairs.

We also used to ride bikes around the construction zones that had jumbled mounds of dirt. One time the grip on my handlebars slipped off while I was going downhill on one of those and the bike handle gouged the shit out of me. A friend of mine around the same time broke his collar bone and had to wear a sports bra for a few months.

meters

No one uses meters in America except for communists. I didn't think you were but now you're suspect. O.o

You're probably in your 40s? When I was a kid was when people started being overly cautious. I would climb poles and trees and people were banging on our door to tell my parents.
