"at" at end of sentence

[Douglas Bigham]

I'll add to the "general south midlands" for final "at".  I've got it,
everyone around here  has [got] it.  But it's not so common that I don't get
railed on for it every so often.  Slightly different topic... does anyone
else know the response:

Q. Where's it at?
A. Behind the at.

This is the typical smart-ass response for any final "at" question here, and
I was wondering if that was regional or as widespread as the "at".
