A fishing friend of mine was surf fishing in SC a couple weeks back and while he was tending his rods something caught his eye to the right side of him, he thought he was seeing things but found out it was a 10 foot gator and thought that they only lived in fresh water, he called a park ranger and they came out to see if he was drunk or smoking something but to their surprise they saw the same thing and then called in someone that could capture it alive. Found out later if a gator is injured they go to salt water to get heeled. I don't know if that's true maybe someone else would know.
