My Father pulled one of those off when I was about 12 years old at Cedar Point. We were on one of those hilly roller coaster rides. When we left the station, my lap bar released. I told my Father. His arm came down across me like a steel bar. He literally held me in at the top of the hills. I’d have definitely been ejected otherwise. We of course told the people running the ride when we got back to the station. They shut down the ride for a little bit and took that train offline.
Great story for the thread!!
