How are you planning on hunting? Working birds to decoys on the water or pass shooting/sky busting at high flying geese going to and from the prop area?
If you're going there to hunt on the line with the intentions of pass shooting at high geese, don't do it. Might be legal but pretty unethical knowing that any number of the birds you shoot, even if you stone them, are going to fall into the prop area. Not to mention there's nothing worse than a sky buster on public land
If you're gonna set up on the line, work geese into decoys and shoot 'em in the face when their feet are locked then you should have no problems and nothing to worry about. Quick follow up shots when they hit the water and so much as twitch.
Cripples happen sometimes. Even to the best shooters. Put yourself in a situation and use methods that lessen the likelihood of birds going into the prop.
