We have them all in Georgia:
Copperhead
Pigmy Rattlesnake
Timber Rattlesnake
Cottonmouth (water moccasin)
Eastern Diamondback Rattlesnake
Eastern Coral Snake
But in north Atlanta it is mostly the copperheads (in my experience). I mostly see non-poisonous snakes often in the spring and summer when hunting. I just leave them alone. The danger is not seeing a copperhead and bungling in on the snake, reaching down without looking or stepping on one. I stay out of places with lots of brush in the spring and summer because you cannot see a copperhead and hard to hunt in that brush anyway.
I just watch the non-poisonous snakes and let them go on their way. If they don't wish to leave I just nudge them with the coil. If I am unsure of a snake's identity, I move on and hunt elsewhere.
As a teenagers we used to hunt and catch non-poisonous snakes and keep them in a cage for a few days to show off to friends and release them.
Hognose snakes are the funniest snakes. Touch them and they turn over and play dead until the perceive the treat is gone. King snakes are cool and often very gentle if you don't move your hand in front of their face. All water snakes have a nasty disposition and are best avoided. Black racers are also aggressive and mean tempered and big ones have big bites.
Have been bitten about a dozen times as a kid. Really does not hurt much at all but bleeds quickly. Should always get a tetanus shot after a non-poisonous snake bite. But I usually was up on my tetanus shots so never really got any for non-poisonous snake bites.
Have handled one rattlesnake as a teen, but that was stupid. Fortunately all was ok.
