I went to boot camp at Great Lakes back in the late 70s and then later, after I was commissioned, served there as a division officer. I can remember back then, both as a just-graduated boot and an officer, being able to walk pretty much anywhere after getting off the train from North Chicago and Waukegan, even late at night, without having to worry about dealing with the “wildlife.”
Now? “Bad day in Bosnia” comes immediately to mind. ;-)
