Probably too late for this but I always like the idea of a drive in movie, we can easily download some really bad hot rod movies for free, we just need a screen and DVD or CD hookup. I have a collection of old drive-in ads.
I brought a projector a few years back, but it just wasn't bright enough to be useful in the daylight. I suppose we'd need a proper screen, which could be tricky.
I can tell you that a 42" screen will fit in the back seat of a Mark, but no. I'm not doing that all the way to PA..
I just bought my show field ticket under LOD. I am only there for Saturday but hope to get some great ideas and good weather. I gotta get my car ready!
