As a kid I never hesitated to jump into the water, never. As a grown up after seeing some of these massive catfish and stripers, I'm a lot more weary of getting into the water. I know the chances are slim you ever come into contact, but damn those fish can get big.
Don't even get me started on Goliath Groupers that love bridges and structures in what I would consider shallow salt water areas. On top of it all they are ruthless fish.
