Used to love going to the Coral 4 on long weekends for the Dusk til Dawn. For the brave it was free if you trunked yourself in past the gates. Other drive ins I remember going to have all closed. Too bad! Can't see them coming back though.

All that is left to do is to go and geocache them to pay tribute....
