Yes, snake boots would be a neccesity here. I have only lived here ( south west GA) for about 14 months and have seen 12-13 rattle snakes, 2-3 moaccasins and countless non venomous species. Even in winter months the temp doesn't drop below 60's in the day. Probably 5 out of 12- 13 rattlers were seen in Oct - Dec range. Though they were not really responsive they were out of the ground. We actually have a festival here in Jan. called the "Rattle Snake round up" I hope this was of some help to you.
Absolutely needed and necessary.
As waltor stated it doesn't get cold enough for them to completely stop moving about. Those Cottonmouths can be really aggressive and will come looking for trouble.
If you will be wading thru water or easing along swamp edges I would go a step farther and get some snake proof chaps as well and watch your hands, most snake bites are to the hand/forearm area.
Winter is tough on whitetails, that is an accepted fact.
You can help the quality of your herd by providing winter plots - that are not necessarily designed as kill plots.
Having what I call green plots - that the deer can browse in when most of the other food is gone, can greatly benefit the deer herd when they need it most.
Come December - at least in our area of the south - most of the mast is gone, all of the crops were long harvested and this green browse can really make the difference for...
