Completely agree. Had a friend that worked for a carnival in his younger days. Told me he'd never ride a roller coaster, he knew how they were assembled.
That is my attitude. Every one of those rides has a “Jesus nut” which is coincidentaly what we called the one that held the Rotors on the Chopper. One nut, that if it fails or comes loose, really bad things and death can happen. These things at the park, are put together by drunks and tweekers, Carnie’s if you will.
