We live on a lake and have had our share of gators. We have the "grandpa" who is about 11-12 feet long. ...Haven't seen him in about 8 months - but he's out there, somewhere.
Earlier this week, our neighbors called the police because one (about 6 feet) came out and was sunning in the middle of the road.
Anyway - my word of caution.
Normally the gators around here pretty much keep to themselves. But where you have to worry is when you stumble up upon a nest. They are VERY defensive! Our lawn guy accidentally came upon a nest a few days ago. He jumped into a nearby boat, where he was literally held hostage by the gator for a few hours, until he could reach someone on his cel phone for help. When they came out, the gator lunged at them, so they shot them. In this situation, it was self-defense and legal.
So be careful when walking near the brush around lakes and waterways - there could very well be nests there...
