I like the new system...but I agree with a previous poster that Paulding should be lumped into Metro ATL. I'd drive there for a deal in a heartbeat...but not so much for something as far NW as say Chatsworth - unless I was already headed there for another reason (like visiting my extended family up there).
I think you guys are reading a little too much into it. It isn't meant to be a strict thing, it is just a quick glance to see if something is near Atlanta or Savannah. If you are near a border of two of the regions, just put the one that you feel applies the best.
