I hunt the bay a lot. If you venture out upon the flats at high tide, you will get stranded. Better option is to go out on the low incoming to learn the channels. Grass tussocks and marsh will stay dry to 9' high this time of year. Geese use the edge near the grass, which allows a good hide. Barren flats are an all out effort and prolly a wate of time. Main channels with good flow generally have sand and can walk easy. Watch out for cuts on top of the marshes. They can break a leg or drown you quick. Some are only one foot wide, and six deep.
