Real tough water back there the further you get west. I have hunted a few spots around lakes bay and there are a ton of black ducks on the marsh but mostly brant and buffies toward the bigger water. I learned how shallow it was on a NW wind one night when I had to pole for more than a mile to find enough water. Have not hunted scull bay but it appears to be real shallow. If you watch your tides and wind I think it could be good, especially when things freeze up inland.
Don't know about the blind - do you mean the sand mounds behind Longport?
