When I saw this thread title, my first thought was the ranges at Camp Matthews where MCRD boots went for rifle training in the late 50's. Happy to see others with the same kinds of thoughts. There were days when "Maggie's Drawers" really got a workout, and there were often characters who "accidentally" fired at them. It's a hoot to now have a sense of where the label came from. Now, if anyone can come up with a plausible explanation of how the pits came to be known as "the butts"---.
