When I first moved to LA in 2002, I was terrified of the gators, water mocs, coyotes, feral dogs, and hogs, but refused to stay inside. After a few years, a friend suggested a pistol (revolver for reliability, chest holster for access), and I was cured. Seldom had to use it, entirely on water mocs, but had a run in with a drunk on a mule that did cause me to consider it... that ended fine for both of us when i realized he was too drunk to hurt me, and the mule had no interest in doing so.
A friend who grew up running the LA swamps as a youth told me that he once 'cornered' a 13-15' gator while poling his pirogue up a very narrow channel. it disappeared, and after awhile, he decided to continue on forward anyway. reaching his purpose, he got out, turned the boat around, and proceeded back home, passing the spot where he'd "lost" the gator, and never did see it... he told me he thought it had simply "gone to bottom" when it saw him, and that he'd passed over it both going and coming back without incident. He said they generally have no interest in hanging around humans.
Conversely, I went to visit him once, in a New Orleans suburb, and we took a bag of marshmallows down to the water's edge one evening... his young son took a branch, climbed down a ladder to the water's edge, and began to beat the surface with it for a long minute. My friend then shone a light over the water, and dozens of eyes had appeared, all moving toward the ladder... apparently, they like marshmallows...
