There used to be a place called "Cadillac Cliff", which was about a 300 foot steep embankment into a creek bottom ravine, in the hills southwest of the town I grew up in. It was common for a small group of local n'er-do-wells to steal a car, joy ride in for a while as they drank a few beers, then roll it off Cadillac Cliff. You needed a 4-wheel-drive to get to where the stolen cars landed, and they were never recovered due to the expenses and complexity, so it wound up being our no charge - pick your part and remove it yourself wrecking yard. We pulled some good stuff from there, such as Muncie, Mopar A833 and Borg Warner Super T10 4-Speed transmissions and Mopar 8-3/4" rear ends.
