dude i live in southeast tx and can definitly confirm the cottonmouths. i wear uninsulated lacrosse boots and have been tagged 4 times in them. only one time did any venom get through the boot. luckily the fangs didnt even scratch me. i have been a waterfowl hunting guide for ten years and swear by lacrosse. good luck huntin and if you dont see many snakes give them a try they are super comfy.
