Can you dig down into your childhood memories to a favorite movie theater? Remember the carpet, as you crawled around for the popcorn you spilled? Remember the faded ceiling paintings or the chips on the molding? Remember the stories older kids told about the rats that raced over their toes when they sat way in the back? Was it old, did it get torn down, has it been preserved?
Whatever the case, you can propably find the place at CinemaTreasures.org, drilling down to country and state. California (with 1875 entries) is here.
Danged if they don't have every place I could think of, including the 1938 Strand Theater at Torrance and Catalina in Redondo Beach. And it became history in the 1960s!
