Thanks Danny. I've spent several days of my life looking at a bridge similar to that, many good memories. Now at least I know that it was Goliath Grouper breaking me off and never getting them turned. I didn't own the tackle or the smarts to ever get to see one, much less land one.
The fenders of which I speak are at the mouth of the St.Johns on the south end of George and usually hold some current and can be tough to impossible to fish in heavy flow. They can hold some banner size fish at the right time. I never passed them on my way anywhere.
