Opened in Vernon, New Jersey’s in 1978, Action Park’s biggest claim to fame was the number of injuries experienced by visitors to the amusement and water park. Apparently during Action Park’s heyday, between 5 and 10 guests ended up in the emergency room every weekend. It was nicknamed “Traction Park,” “Accident Park,” and, my favorite, “Class Action Park.” Lawsuits finally shut down Action Park in 1996.
