Pete,
I haven't read the thread posted but I will share my experience living and hunting in snake country.
I am a yankee, grew up in northern Illinois so I was not exposed to snakes the bite or swamps. Most of my snake encounters occurred in early fall during bow season or spring turkey hunting. I never felt the need for snake boots. Early mornings snakes are pretty lethargic. When out walking in the woods during the days I was usually trying to be quiet so I was watching my steps. I was more concerned about my Lab getting bit than me.
A buddy of mine, from New Jersey, had a rattlesnake curl up at the base of the tree he was in one evening. When he climbed down he jumped away from the tree. Using he flashlight he could find the snake so removed his climbing treestand and finally made it to the truck. I figured he had shot something since he showed up so late.
Dave and I were a couple of yankees who had a lot of fun in the woods and swamps of north Florida. But, we sure got ourselves scared a few times worrying about what was out in the dark! The worst was coming across an armadillo in the dark.
