Saw a herd similar to that between Newnan and Peachtree City once back in the early 80's. I counted 33 after I first noticed them crossing the road. I had to stop counting when a car on a side road came up and pulled out in front of me. I counted 28 one night in the late 90's in the cemetary at my church when I was going to the store across the street but that was only part of them.
