Harstine is a tough game for Dungies... Tons of Red Rock. Blackmouth in November is different \:D

I was going to mention the Delta too. Try out fairly deep (about 100') near the tracks to the east. Another spot worth a go is the south end of Ketron. The island will provide a lee on the flood tide.
