You hunting in Frank Williams fields down there by the dismal swamp?
I have killed right many in there myself. If you need/want a group to go, a good friend of mine takes guys on swan hunts down there. No charge, not a guide. He is a retired military man who just enjoys good company. Takes several people every year. Puts out a 1000+ bird spread. Nice thing about those fields is you can hunt 10 groups in there and not even hear each other shoot they are so big.
