I have never hunted them, I have seen a couple at Blackwater refuge and they do hunt them there,http://www.fws.gov/refuge/Blackwater/visit/hunting.html, also at the other two places you mentioned. Your best bet would be to call MD DNR and ask questions. Blackwater is close to Cambridge. You will need to hunt them in the sloppiest thick mosquito infested are you can find and most people hunt off the ground because the cover is thick. If I were you I would contact Blackwater and the MD Game dept as soon as possible and ask lots of questions.
