The drive-in of Umlaut's childhood was the Sunnyvale 1 & 2:
I have vague memories of seeing Tora! Tora! Tora! and Beneath The Planet Of The Apes at this drive-in... but can't remember what else. It was less than a mile from my parents' house; as a kid I was fascinated seeing the movies on the screens if we happened to be driving by the theater at night.. and it was cool how you could sneak into the theater during the day when it was closed (which is how I took the above pic).
Sunnyvale 1 & 2 has been gone for years, covered over by condos... Another time, another place.
