They were actually called the Flat Bed Ten. (Jerry's just having some fun). And they were from Lake Elsinore. They didn't want to hike the whole trail so they moved a barricade and drove a flat bed track up a closed road. And you know, to Rangers that's the equivalent of murder.
But they weren't the only reason the legal jumps were stopped as there were plenty of other skydivers breaking the rules. Jumping with no permits, jumping after their permits expired, or a day before their permits were good, also jumping at night, doing RW, and so on.
But one thing you have to keep in mind is the Park only agreed to try the legal jumps mainly to gather enough ammunition to shut down jumping forever. And after it was over they had it, "See, these guys can't even follow some simple rules."
But it also needs to be said these weren't B.A.S.E. jumpers, they were skydivers. Skydivers out on lark and taking things about as seriously as skydivers take anything. So I've never gotten too mad at them even though we've been paying the price all these years later. But the simple fact is the Rangers had a plan and we didn't . . .
