You will be amazed by Hamilton's specifics. He tells you where to park, how far to walk, when to turn right or left, and so forth. "Park here, walk there, turn left at the rock, and go until you see the fish." "The bottom is soft here, it's grassy there, and be sure to wear boots in this place because the coral is sharp." I have been to, and fished, about half of the places that Hamilton writes about in his book. And what I read is spot-on. Granted, storms and such might eventually mix things up. But the lay of the land he provides is as accurate as anything you will find in print or online.
