Rode my vintage 10 speed (it wasn't vintage then) on a busy downtown street while a festival was going on. Tons of people walking around, buying food, sitting in lawn chairs. I was about 12. Trying to look cool. Failed to notice gutter with slats about the exact width of my front tire, which lodged in them, sent me over the handlebars and onto the ground face first. It was like those teen adolescent movies where hundreds of people of all ages are laughing uproariously at you.
