"About 45 pounds," says Keith, who makes his living as a timber cruiser near Jackson, Mississippi. After 25 years, he can guess a fish's weight just by touching it with the rod. "Keep that door blocked good, Ricky. He'll make a break for it if he can." Ricky Lyles -- who is half Keith's size, up to his neck in water, and who can't even swim -- is grinning wildly. His job at the moment is to block the door with his feet, leaving just enough room for Keith to turn the fish around with the catfish pole. Even the dozen or so of us along for the ride in johnboats a few feet away can hear something trying to hammer its way out of the box deep under the rolling water. It sounds like a bull stuck in a linen closet. Welcome to hand grabblin', Mississippi-style.
