From 1978 to 1996 — in summer movie terms, from Animal House to Twister — Vernon, N.J’s Action Park waterpark flung thousands upon thousands of sunburned, liquored-up, party-down thrill-seekers headlong into a notorious collection of poorly designed water slides, a 65 km/h concrete Alpine coaster where the brakes didn’t always work, and 100 km/h go-karts. According to those who worked there and depending on the driver’s risk tolerance and blood-alcohol level, the go-karts sometimes veered off course and straight onto Interstate 94, which bisected the park itself.

From 1978 to 1996 — in summer movie terms, from Animal House to Twister — Vernon, N.J’s Action Park waterpark flung thousands upon thousands of sunburned, liquored-up, party-down thrill-seekers headlong into a notorious collection of poorly designed water slides, a 65 km/h concrete Alpine coaster where the brakes didn’t always work, and 100 km/h go-karts. According to those who worked there and depending on the driver’s risk tolerance and blood-alcohol level, the go-karts sometimes veered off course and straight onto Interstate 94, which bisected the park itself.

Everything about Action Park could kill you. And it sometimes did, as the wittily appalling HBO documentary Class Action Park makes clear.

The half-wisecracking, half-serious reminiscence grew out of an earlier 15-minute documentary, The Most Insane Amusement Park Ever. That title does not lie. With little safety oversight and, eventually, a series of fatal accidents, Action Park operated as a place where the usual rules of theme park engagement didn’t apply.

As more than one interview subject notes, it was like an ’80s movie about latchkey kids in over their heads, running loose and wild.

Comedian Chris Gethard — a terrified Action Park regular as a kid and the ringer here — equates the experience to a rite-of-lonely-adolescence passage. “We felt like we were on our own,” he says. “We felt like the world was an unsafe place.” Action Park confirmed it.

Millions of kids in America can tell you about the stupid stunts they pulled, or the time they went way over the line trying this or that. Action Park was made for those kids, and their knucklehead parents.

It had the deceptive distinction of offering a heavily advertised, healthy-seeming chaotic day in the sun. It promised excitement and it delivered, complete with skin abrasions, snake-infested lagoons where the “Kayak Experience” attraction was located and far, far worse.

The park’s huckster-founder, Gene Mulvihill, provides the focus for writer-directors.

A disgraced but well-connected graduate of the Wall Street go-go years, Mulvihill bought two ski resorts in the Vernon township and realized he could make money in the off-season by building a waterpark of his unbridled dreams.

What was touted as “the next Disney World” became a down-market expression of pure adolescent id, where “you control the action!”

Eighty kilometres from New York City, Action Park featured three main areas: Alpine Center, Water World and Motor World. The Cannonball Loop dominated the talk at Water World. A long, high, steep tube, wetted down by sprinklers, sent customers plummeting into an upside-down hell before skidding onto a too-short runway puddle.

Some of the craziest details in Class Action Park involve the initial testing phase of this attraction. Park security director Jim DeSaye recounts Mulvihill paying his employees $100 to try out early iterations of the Loop. The first two kids, he says, came out with their “mouths all bloody.” The next two came out with substantial skin lacerations, from the stray loose teeth embedded in the tube’s padding.

“Gene didn’t believe in the concept of insurance,” Porges notes on-camera, detailing the Cayman Islands shell company Mulvihill established to self-insure, minimally, a business built on adrenaline and terror.

Summers came and went, with the stories of dislocated shoulders and other injuries piling up. It was a pretty rough crowd, and fistfights broke out routinely, waist-deep in the “Colorado River” traffic jams.

The documentary’s second half turns darker. Several patrons died, either from massive head injuries or electrocution or drowning, between 1980 and 1987. Among them was 19-year-old Sussex County resident George Larsson, whose mother, Esther Larsson, serves as the film’s conscience.

Throughout Class Action Park the filmmakers link Mulvihill’s unregulated lethal funhouse to the larger, deregulated capitalistic greed of the Reagan era.

That’s not a stretch, exactly, but the documentary infers a good deal about Mulvihill’s underworld connections and political manoeuvres without quite nailing them down.

Relying heavily on park employees’ memories and stories, it’s well worth seeing nonetheless. The ‘80s trappings, particularly the synthesizer-heavy score and the funsy animated segments, evoke memories of a time before cellphones and helicopter parenting.

Former Action Park lifeguard Faith Anderson remembers, with some fondness, the “Lord of the Flies” behaviour of the boys and men, and girls and women, who loved the place.

She also says: “I think our parents should’ve been more afraid.”

Officer who shot dog dead after it bit him won’t face charges

A Manitoba First Nations police officer will not face charges for fatally shooting a dog last year, despite the Crown describing the officer’s conduct as “concerning.”

The Independent Investigation Unit of Manitoba announced it would not recommend charges Monday, more than a year after the incident was reported to the police watchdog.

A Manitoba First Nations Police Service officer went to a home in Swan Lake First Nation to make an arrest in June 2025, the IIU said. No arrest was made as the person police were looking for was not there. As the officer was leaving, a dog chained outside bit him.

The officer later returned with a carbine rifle and shot and killed the dog.

City rescinds Balmoral Street property owner’s order to clean up encampment

A West Broadway landlord is off the hook for clearing a large riverbank encampment after the City of Winnipeg rescinded an order threatening to stick him with the cleanup bill.

Marvin Sharp, CEO of Astroid Management Ltd., which operates the Pen-Eve Apartments at 35 Balmoral St., said he received a call from the city Tuesday letting him know the order has been cancelled.

In a statement from the city, an official said the order was shelved due to an existing and active easement on the property.

“We have been communicating with the property owner throughout this process and they have been informed of this development,” a spokesperson said.

‘Take it to the bank’: premier insists temporary ER will open in Dauphin by Labour Day, but nurses skeptical

Carol Sanders 4 minute read 6:34 PM CDT

Premier Wab Kinew insisted Tuesday that the flood-shuttered Dauphin hospital will have a temporary emergency department in place by Labour Day, but offered no details on the plan.

“I’m here telling you, take it to the bank — Labour Day — emergency department services in Dauphin,” the premier said when asked about it at an unrelated news conference in Winnipeg.

The Dauphin Regional Health Centre was forced to evacuate 54 patients and close its doors on July 1 after the Parkland region experienced severe flooding.

“You’re going to see temporary structures being stood up there over the next few weeks with an opening day of Labour Day because we know how important health care is to people in Dauphin.”
