way back in 2005, my friends and I hunted out of Crisfield, MD for a week. I believe that area is called the Pokemoke Sound. The tides are wind-driven, and depths vary from 1-6 feet. At low tide, it is very possible to be stranded on the mud, as we were one day.
We had private housing, but there are hotels in the immediate area, and a good harbor in Crisfield. We hunted mostly in Maryland, but had Virginia licenses, too, and hunted below the border at least once. The state border is marked by large telephone poles. We hunted around the area of Great Fox Island and the small bays and islands surrounding it. Check it on google maps, and you'll see where I am referencing.
At night we could hear very distinctly the loud flocks of widgeon on the water.
Our week's bag included all the puddle duck varieties, along with bluebills and redhead divers, brant, and canada geese. The diver flocks were numbered in the 1000s. It was the hunt of a lifetime for me, and I would recommend that area to you if you are of a mind to go there.
You'll need to bone up on local laws, I think. We had a local guy with us and he knew what we could do and not do.
BTW, Crisfield is home to some historic decoy makers and great seafood. I think their high school mascot is the crab.
Hope this is helpful info. good luck.
