They sure won't. They are still the best thing I've found for hunting in Florida weather. The season is still young and eventually the mud will get crusty from frost but so far I've hunted more days when the teperature was above eighty degrees than below. That snake had the right attitude. It allowed me approach from behind and walk around and squat for a closeup shot. I kept my barrels between me and it just in case it got stupid. It never opened its mouth and only extended its tongue to smell the barrels which were less than a foot from its head.
