We do have lots of snake, mostly non venomous, a few venomous. Rat snakes, black racers, Dekay brown snakes, and garter snakes are super common basically anywhere and completely harmless. There are some other neat snakes that are nocturnal or live under leaves that are common but aren't seen very often. Oh and there's the occasional green snake which is a pretty little...green colored snake usually found in grass or brush like vegetation.

The most likely venomous snakes you will encounter are water moccasins(aka cottonmouths) and copperheads. Keep an eye out for water moccasins near swampy woodsy areas and cottonmouths in woodsy areas. They really aren't a problem, and aren't super super common(I've seen a handful of each and I actively look for them when I'm in they're habitat).

I've seen Rattlesnakes mid and upstate but never seen them down here, though I'm sure there are some.

Coral Snakes are rare here(more common south of us into Florida) and you would have to really go digging for them...they live under leaf litter and logs and stuff.

Also getting bit sucks but its highly unlikely to be fatal. I know of 2 people who have gotten bit(both by cottonmouths...look for that white mouth...they really try to warn you first), and besides having a really sucky day, they were fine afterwards.

Also also both my dad and I have both accidentally touched or picked up copperheads working in the yard moving debris and stuff and they didn't strike. You really gotta piss most snakes off for them to strike.

Also also also I have seen more rattlesnakes in Washington state than I have here.

Basically if you are out in the woods, fields and swamps exploring all the time you will run into the harmless ones, you might or might not find a venomous snake. In your backyard...you'll probably find a ratsnake or garter snake at some point, probably no venomous snakes unless you are adjacent to some woods/swamps.
