I just called the number back and got a message saying that it was the Georgia State Troopers Assn fundraising drive and that I'd be getting a call back later--yippee!
I live in Columbus, GA and I've gotten a call from this number at least once a day for the past 5 days. It looks like everyone responding here is in GA so the post about the Georgia State Troopers Assn sounds right on the money (so to speak).
