I spent part of 1976 on Mare Island, FT C school. Very interesting place.
I grew up in Vallejo. Both my parents were federal employees at Mare Island. My Dad was a nuclear inspector on nuclear fast attack submarines and my Mom was in personnel. I knew many Navy submarine sailors and government employees in our church. After my Mom retired, she was the head docent at the Mare Island Museum for many years. My Mom’s name is in the acknowledgements for the USS Indianapolis book by Lynn Vincent and Sara Vladic.
