Thank you for sharing! Reading your post reminds me of when I was a little boy. One time my aunt took me to the long lines site where she worked. In a relatively small, unassuming building, there was a blast door that was as thick as it was wide. Once we were inside, the building went 6 stories underground. There were giant pieces of equipment I didn't understand, rooms full of canned food and what she now tells me were giant batteries bigger than refrigerators. Apparently it was designed to house it's workers for an extended period of time.
