The spoon's qualities make it a prime artificial for snook. Once you arrive at the river of your choice, it's not that different from fishing other places for snook. They all signal probable strong current flow, and that is the hallmark of Mr. Linesides. He like moving water. These should be really good spots on the outgoing tides.
Most rivers have at least a few islands scattered along their lenghts.
When you find them, fish any point that has a yard or more of water along the shore. The same goes for any depressions or potholes you might find in the area, as long as you've got moving water. Spoil piles, sand bars, oyster bars, and flats that have current flow over them on incoming tides are also likely places to find snook. The rising bottom will tend to stack bait up on the front side and makes a nice little snack bar for the snook to dine at. Where ever you're fishing on a cold winter morning, try to fish the spots that are on the north side of the creek, river, bank, or bar you're fishing.
