Free: Contests & Raffles.
I've shot em and I've lost em to this very thing, at least what I was told by the people who taught me how to duck hunt. In the old days I did'nt have a retriever. I retrieved my own. I'd use my float tube. Id go out and hover where they went down. I dislodged more than one and they floated up and I was able to get them. They were dead. I've also hunted with a guy with a good dog who would dive and get them. That was cool!
