Cool idea in theory, and the only drive in in the Valley, I'm pretty sure.
however, the quality and service around here is kinda poor. You get two movies for the price of one, which is nice, if you can sit in your car that long.
they've scrapped the sound box, and you just tune your radio to the right station, so you better have a working antenna. your best bet is to take a truck or SUV that you can lay the seats down, pile the kids or dogs and blankets in and go in your pajamas. of course, as teens we would also sneak in beers, but i'm sure that's frowned upon officially.
