Reminds me of a show I watched as a kid. These people row a boat up into a grotto and end up in a land of dinosaurs. NO...it wasn't Land of the Lost. It was a serial that they use to show on Channel 5 in Charleston on the Happy Raine show. Charlestonians and lucky Savannahians will remember her as the Piggly Wiggly lady also.
I remember that same show too! There's a trivia question for ya.
