I enjoy your tips so keep them coming, Paul.
I know w/out a doubt there is plenty of PI in Georgia though. I think I'd color in that state on the map. I also see a difference in Poison Oak and P-ivy, too. I've never heard either of those referred to as climbing sumac though but perhaps that's a local name for some areas. Sumac usually has many more leaves than 3 per leaflet.
