If terrain parks were no longer existent, I would be so bored (and broke because I would be out of a job) that I would go buy a car, slam it into a wall, then sue the car company for making a car that I could be hurt in. If that doesn't work, I'll sue the Police for not stopping me from speeding before I hit the wall.
Then I'll have millions and millions of dollars so I'll pay Britney Spears 18M to sleep with me and I'll buy a big tramopoline that's the size of a football field, and I'll get naked, bald midgets to oil wrestle on it. Then I'd buy a ski resort and make it one big huge terrain park with no insurance whatsoever. Then someone would hurt themself in my park and sue me so I would be broke again, at which point I would have to come up with a plan to sue someone else so I can buy another ski resort and repeat the process.
