re: Thoughts on duck hunting these days

2 years ago I made a duck hunt on RealFoot Lake in Tennessee. The guide was telling us about part of the lake that borders a Wildlife Refuge, said it is called "The Firing Line". Ducks come flying off the Refuge, over trees, and hunters are lined up all along the border. All they do is skyblast the ducks as they fly over. The ammo manufactures like them, the guide said they typically shoot a case or two of shells in a weekend.

I don't understand how someone would even want to do that!
