Lots of areas with lots of birds! Get a copy of the atlas, for sure. I have had luck around Lovewell state park, but be sure you have a Thermacell! I have never gotten into mosquitos like that before! CRAZY! Some other buddies have had good luck around Kanopolis, too.
I have also killed birds on 20 acre WIHA patches. Basically, we will pick a large WIHA or state park as a "base" camp and we will road scout the small WIHA areas looking for birds or birdy places to hunt.
