Ha Impulse-ive! I would have made you pay for a LOT more. Nah, I'm just playin', I'm not THAT mean.

I know of an incident that happened at The Great Escape. My friend's mother was exiting The Trabant. Now if anyone had been to the park in 2003, they would know The Trabant had it's entrance and exit on the west side of the ride. It was kind of an odd position. Anyway, while exiting the ride my friend's mother tripped. It was very easy to do. She ended up with a broken ankle.
Is this the park's fault? Sure is.
Is it fair? Maybe not.
The next year we returned to the park and found The Trabant to have it's entrance on the east side of the ride. This was a huge improvement. I'm sure this particualr incident was not isolated. The park had probably received several complaints and, because of legal concerns, decided it was in their best interest to make a change.
How about Dragster? If this incident were to happen again, the park would be hit with another law suit. Would everyone disagree with that as they have with this incident? I would say no since the incident had already happened before. Should the victims of this hypothetical "future" incident be granted more money than the current ones? No.
Whether the park saw it coming or not they are still liable. It's like the, "if a salesman trips in your yard, you can sue him" bit. The only difference is the park is ALLOWING people to enter.
Impulse-ive: If you did that with your park, you would probably never be sued. Still, I'm not sure many people would take that risk.
