Living and driving here in the Deep South (and these two things are intimately connected), one thing you quickly learn is that down here, you never, ever use your horn.  It's considered rude and ill-mannered and will most likely result in the direct opposite outcome than you were intending.

So it's with interest that I note, on my horrible, horrible drive home from work tonight, as the much-praised Waze app seemed to lead me from one appalling traffic jam to another, that the congestion has gotten so bad that I actually heard Atlanta drivers honking their horns while stuck in traffic.

Literally, it's a first, and another omen of the impending apocalypse.
