I wear hiking boots with gaiters from Academy and watch where I step. Don't carry anything to kill a snake with as I let them go. If I run across a rattlesnake or copperhead all bets are off. This one was waiting on me at camp when I got back Saturday. Gave him a little nudge and he went back to the woodpile.
When I got my hunting land, I found a few of these, this one of the longest. Couldn't tell what left this but I figured as long as they stayed out of my trailer or deer stand all was good. I thought about getting some snake boots or at least a snake stick but ultimately figured I had gone this long without them so decided against it.
I don't carry anything specifically for snakes, but have used what I had handy a couple times. Most have just been unlucky enough to surprise me, one that was just inches from my leg rattled it's tail under the leaves to simulate a rattler, 12guage with #7 (was dove hunting) took him out, turned out to be a hog nose. Another was a cotton mouth that decided it was a good idea to slither across my boots while my my battle buddy was digging a foxhole during a field exercise, kabar to the neck and into my mess kit with that one...1SG chewed me out over that one, after our LT told him the snake I cooked was great. But when they give me the courtesy to let me know they are there so I can take precautions, they are safe from me, specially if they are non poisonous.
This guy decided my worm looked good enough to eat, took a bit to make him spit it out but after a few minutes he got to swim away.
This one stayed around almost an entire day while I built my new deer stand. He was close to my toolbox, so had to constantly keep going by him. He too got to slither away, as do most garden snakes that are around the house, unless I accidently get them with the mower.
