you would be very wrong on that guess he also has several ponds and a couple creeks that go threw his property (well the one he lives at i havent been to all of the ones that he over sees) fished and swam in them all the time growing up and had quite a few run ins with hots as well.
14lbs or 1400 if something gets tagged by a hot it would leave some sort of in most cases and still havent heard any of those.
plus 1 bite out of 150 goats on 80 acres in prime cottonmouth country thats pretty low considering how dangerous they are that they have to be killed to protect your livestock. either you killed more than your saying or they are not as dangerous as we think.
and compareing killing a hot to killing a wolf, moutain lions etc is wrong. a moutain lion can be an actual threat to your livestock as they see it as a food and a snake only would bite them in order to protect themselves.
