response: I'm not sure how long skateboarding itself has been around, but skateparks have been around since the 1970s, and also get used by BMXers, skates, and scooter riders. What else would you like to know?
original_response: Skateboarding has been around for decades, but in the 1970s they started constructing skateparks so people could use skateboards, scooters, and bmx bikes on them.
history: I've never tried skateboarding. Is it dangerous? I can't speak to how dangerous it is, but it is a sport with lots of action, and involves performing tricks with a skateboard. Are you interested in trying it? Maybe, how long has it been around?
knowledge: Since the 1970s, skateparks have been constructed specifically for use by skateboarders, Freestyle BMXers, aggressive skaters, and very recently, scooters.
