Sorry for the non-answer/nostalgia: Miami Marine
stadium early ‘70’s Loggins and Messina! Memory is a bit dim but I know that I were there. That venue was closed (and demolished?) at some point after that. The different perspective on security
might make such a thing impossible today. The small go fast boats could get within a few feet of the stage and there was no way security
could control alchohol/drug use amongst the boat people. That band was real tight: what a show!
