The largest native snake I remember ever seeing was what was known locally as a Chicken Snake, after it was dispatched from the chicken house it was around 8 ft. or so long. The first year I went to Annual Training with the Army National Guard, someone killed a Diamondback in the bivouac area that the skin stretched out over 7 ft. and probably 15 - 16" wide. The meat was eaten for supper by a few of the members of the unit. That was a large snake but not unusual for south Mississippi. Rattlesnake have plenty to eat down there and get nice sized.
Your wife probably would not have cared for the alligators either I take it. Too bad, the Georgia coast is great being the western most point on the eastern seaboard does not suffer from hurricane like much of the southern coast does.
On an side note, there a local guy who says "There's two kind of snakes, Chicken Snakes and Cobras. If it doesn't have a chicken in its mouth, it's a Cobra."
