Sci- i- i-ence!
( but I really just want the keys to your Ferrari!) I KNEW there was a reason I put this here. This is a Nike missile. They were literallly everywhere when I was a little Buckaroo....The silos were about the size and shape of two garage doors side by side....and they were placed in a grid Acvording to scuttlebutt, there were 265 sites. Fortunately, I never saw one go off and they were phased out completely by 1978....Interestingly, some of these silos are now private residences.
