It's easy to kill a duck, but hard to avoid the ticket. They were writing them up last year, and it was the FEDERAL man, not the NC GW.
There's not much you can do about it, and you don't have any way of knowing if the birds you're shooting are in route to bait or not.
A Federal GW can use his descretion as to how many yards you have to be from a baited area. You can be 1/2 a mile, and if he feels that your birds were taken from a flight zone to a baited area; it's ticket time.
