Strangely enough, two nights ago on tv there was a special about that string of attack/deaths by gators in florida.
After an autopsy, two of the women had been on drugs and most likely passed out right near the waters edge of very popular alligator spots.
The other death was a woman snorkeling. No drugs.
In all honesty, if you are on land with an alligator, you are highly unlikely to be attacked. They are ambush predators and it's obviously not an ambush if they know you can see them. Younger (4ft) gators are a little different and more wiley, they could chase ya. That's when good ole alligator wrastlin skills i learned as a boy in Louisiana come into play. For you city folk, go for the eyes!
