Hello, I'm SearchN. Here is a bit of info. I've been researching drive-ins for at least seven years, and interested in them for many more. I have a website about drive-in theatres (thought out of date) It has been an on and off project. I like to do research at libraries and have several programs I use to locate where they are or once were. Never have met anyone else, other then my wife, who is really interested in doing drive-in research. (if you do contact me) It does require time and effort, but I enjoy it. I started a waymarking.com category for closed drive-in theatres. I only have a few listed as I am still trying to gather more information on others.
