Danner Pronghorn snake boots for me and watching closely where I put my hands.
On a farm I hunt in mid Georgia every year, I almost always have at least one run in with a venomous snake. Usually cane breaks, then cottonmouths and a copperhead every once in a while. Around home in North Georgia, copperheads are the predominant venomous snake with the occasional ratter but no cottonmouths.
If I am ever bitten, it will probably be on the hand reaching for a call or pushing myself up off the ground, snakes seem to move quietly and just appear.
A cell phone is much more important than a snake bite kit.
