Michael, there are lots of creeks and rivers along the bay's western shore south of the Potomac River's mouth, but the charts are not very accurate and have not been updated since the 1950s. Watch your depth finder when entering any of the creeks. I ended up hard aground right in the middle a channel that was marked as 16 feet deep. Fortunately, my Boat U.S. insurance took care of the problem and the guy that towed me off showed me the bad spots, which was most of the creek.
Please be very careful old friend and have a safe trip south,
