Having spent a four years living in Oklahoma all I can say is it had to happen sooner or later.
Huh, never thought about ghat..
An old cuz of mine was a Marine back during Nam and he went to artillery school at Sill. He was one the last, he says, to pop a cap (a 280mm non-nuke cap, that is!) on Atomic Annie. I shutter to think of what his military career would have really been had my old cuz had more than eight toes!
