I've never seen any venomous snakes in the wild.
I've seen plenty of northern water snakes in and around the rivers in the mid-Atlantic, and once when on Big Island in the middle of Lobster Lake, we happened upon a bunch of just-hatched garter snakes or ribbon snakes. And then there was this fellow in Sorrel Ridge campsite on the Potomac in Western Maryland climbing straight up a tree (and over one of the lines securing our tarp. Black rat snakes are equally at home up a tree as on the ground. This one, probably about 3.5-4 feet when stretched out, is a medium sized one. Five and six footers are pretty common.
