Last summer we went to Crystal River and rented a house that had kayaks and a boathouse. On our very first day there, I was sitting on the edge of the property along the canal. I thought I saw a gator in there, so called to my hubby. As soon as I yelled, that alligator turned around and came towards me and went up to the boathouse. No thanks. I ran back inside the screened lanai. We decided no kayaking on that trip.
Gators do not usually head toward a human, they instinctively go under the water to hide.
That the gator was coming toward you indicates that someone had been feeding him in the past, probably several past renters, and that is dangerous. But the gator hears a noise and thinks Din-Din Time!..............
