I have never personally fished them, but here is a link to a map that I think would be a good place to start. It shows the placement of some structure and even gives gps coordinates for some. I am not a professional angler, but I would check out the shallow structure first. If no action there move out and try deeper structure. If you have no luck there, then pack up, go home, call chaunc, and see if you can go fishing with him. He will put you on some fish.
