what ever happened with this association?
do they have a web site?
I have no idea how to answer your question. I did a web search and came up with nothing, however I find the premise interesting. Back in the old days here in Washington there was a company called United Theatres. They owned some theaters, mostly drive ins, but independent theater owners could also associate with United Theatres for film booking. I wonder if someone could set up something similar for the professional outdoor movie operator?
