Have not tried myself, but told by a reliable source:

Two islands between the Narrows and State ramp. Between the two islands is a large flat with a dropoff from approx 12' to 20'+. Bottom bounce or Carolina rig nightcrawlers or chicken liver on the edge of the drop for hybrids. Do not let the bait sit still...bounce or drag slowly. Sometimes the fish will also be roaming the shallow flat if they are not on the ledge. The less boat traffic the shallower the fish will be. Don't know how the moonlight (or lack of) will affect the bite.
