Yes, this is also a concern of mine, probably my main concern on wildlife... Snakes are a problem, we have cottonmouths(water moccasins), and a few rattlers. As careful as I'd like to be, I realize that there is a possibility of stepping on a snake and being bitten. I've debated whether or not to wear a type of leather legging going up to my thighs... Might be too bulky? I'd carry an anti-venom kit, but they can only be obtained through doctors, and only by prescription.
