80000 people play alta - not too hard to meet people. The subdivision can be a little clickish to get into. But once you meet a few folks shouldn't be a problem.
I play out of Georgia Gwinnett College (use to be Collins Hill Athletic Club) off Collins Hill Road near 316. Nice public facility with 12 hard and 4 clay. If that is close, you are welcome to be my guest and come out and hit.
