Here in Ga we have copperheads, and LOTS of them! In my experience or run-ins with them they have been highly aggressive (not just curious). A friend of mine was horseback riding one day and there was a snake crossing the trail about 20-30 feet in front of us; as we waited for it to cross it made a 90 degree turn and came right down the trail towards us as we waited to identify it we figured out it was about a 16" copperhead. We turned around and bypassed the snake but as we went around the snake it altered its course so it would be heading back towards us, nothing exciting happened but that is an example of the basic nature of a copperhead down here. BTW I lived on the North Shore of Lake Ponchartrain in LA for many years and we had plenty of snakes (the first place I ever saw a pygmy rattler) and other reptiles but not even the cottonmouths would put that much effort into checking something out!
Most people around here just don't want to wait and see if the copperhead wants to play nice or not!
That is just my 2 cents.
Now that is interesting stuff. They are all over my camp and I never had a problem with them. I always thought that the only snake that would actively seek out a human and attack it was the black mamba. Which luckily we don't have to worry about
