Dogpatch USA, a Lil’ Abner-themed park in Arkansas, closed in 1993 (you can see some recent pictures at Underground Ozarks; nothing like an abandoned theme park to make you think about Scooby Doo). My family is from Arkansas and I remember driving by the park frequently, always wishing we could stop and go to it. A pretty exhaustive history, including a discussion of a couple of tort suits brought while the park was open, can be found here.
Twelve years after the park closed, a teenager was injured while riding an ATV on the property; his parents sued and won over $500,000. The outcome of the collection process is addressed, somewhat confusingly, in this local TV story.
A story archived on this message board indicates that the teenager hit a steel cable run between two trees. I assume that the suit was brought based on the attractive nuisance doctrine, but that’s just a guess.
