RE: snakes
It's not just in the south. Last year while hunting in Montana, me and a buddy were heading out for an afternoon hunt. I was walking in front and digging my crow call out of my vest and not paying any attention to a snake that I stepped directly on. Luckily it was a garter snake, and not one of the many prairie rattlers out that way.
Anyway...I don't know of a particular snake boot to recommend, I've just heard that they are tough to break in. I've been considering picking up snake "gaiters" that fit over your boot for late season gobblers and early season bowhunting. They are cheaper than the boots that wouldn't be necessary year round.
