The Georgia Historical Quarterly is one of those heavily footnoted publications devoted to the somber study of what we once were. To be truthful, some might consider it stodgy. Even dusty.

Which is to say that the GHQ – for this is how insiderish historians refer to it — is not the place you would expect to find salacious confessions. But to mark the magazine’s 100th birthday, the magazine editorial staff has offered one up.
