Assuming you mean the one near St Marys City and Chancellors Point Park? (I have seen it referred to as St Marys City WMA on some signs, but on others its St Marys City Historic Park)
Never hunted there, but I hike/walk the trail there fairly frequently. I am a pretty quiet walker (I carry some cameras and take wildlife pictures and can usually "sneak up" close enough to get good photos on most animals) I rarely see deer in there, but then again I usually walk in the early afternoon time frame.
Hunting Historic St. Mary’s City CWMA is by making a reservation only 301-743-5161
175 acres. Deer hunting only, beginning Dec. 1st. Open Tues.–Sat. (closed Christmas).
