It's an old screen from the 70's, maybe 100 ft x 50 ft, not really sure. I used to watch James Bond movies there when I was a kid. Would have to be some kind of jury rigged system for it to work. Have to link my PC to the projector. I plan on sitting in my car with my joystick and playing on the big screen provided I can find cables long enough. Unfortunately, I would have to use the drive-in window speakers, the one's on the pole, for sound. Maybe I can splice a couple of them together for some serious surround sound action? As far as advertising the game goes it probably wouldn't work as the surrounding neighbor has deteriorated into a heap of crack houses and opium dens. When those stoners see the planes up on the screen they'll probably think their neighborhood is under attack and barracade themselves in the basement, lol!!! Thanks for your help guys. Free popcorn and stale hamburgers for anyone who wants to attend.
