All the freshwater down here has gators. I ride my bike during the day hours and I often see several just on the neighborhood ponds nearby. Even the smallest ponds usually have one, and at this time of year there might be two (sexy time for gators right now). If you're down here during the winter, no worries, they don't move much and certainly are not hostile. But in the spring, when they are mating, it's best to give them wide berth. However, it's HIGHLY unlikely that you'd be attacked by a gator in the water - probably better chance of getting sucked out of a Southwest jet. When they are on land, a place where they are more vulnerable, they might become threatened if you get too close.
Courses have them everywhere, but I've never seen one become aggressive. Get near and they just slip back into the water. Here's one of my boys and I at Eagles golf course last April. There were a bunch of balls in the shallow water in there and he wanted to go get them - I talked him out of it
