I'm kind of fascinated with the concept of the drive-movie theater...Call it some sort of classic AMERICANA fetish or the like, mainly from a bygone era.
I haven't been to one since I was a really little kid, and hardly remember what it was like. But I read in the local paper that the Buffalo area has an above average number of drive in theaters for whatever reason.
I've heard the audio quality is now decent, they play through your car stereo, and you have an excuse to be out really late at night. In fact some run virtually all night here.
