I'm pretty sure this is a Joro Spider. One of my better spider photos - I took it in China where Joro spiders are common. I didn't know the species until a recent news article highlighted that many joro spiders are now found in the State of Georgia, USA. They think the spider probably came to Georgia aboard a container ship and has now spread. They don't bite humans but do create huge webs which can be a nuisance.
