You want to fish estuary mouths and salt ponds, or any location with moving water. Also look for an area were the flounder can sun themselves. May I also recomend clam worms for bait, and if you can chum broken mussels, I've also heard that rabit pellets work well for chum (the ones that go into the rabit, not the ones that come out
) That, and I would wait until the spring to begin fishing for them.
