We went to the Drive In. And other than the battery dying and needing a jump, it was fine. I hadn't been to a drive in in ages. The audio was crap... the broadcast isn't in surround sound, and a periodic static in the reception. Plus, FM radio doesn't handle changes in volume very well. I had to constantly turn the volume up (for dialogue-only scenes) and down (for the action scenes).
Still, decent enough for $7 each.
