Let's hope they used galvanized and not aluminum. You can't pick up aluminum ones with a magnet like roofers use.
I tend to think this isn't some anti-hunting or eco-terrorism job. Those groups would never get a foothold in Jackson County. This was a response from some hunter that is fed up and decided if he couldn't hunt to his satisfaction then someone has to pay and who better than the guys crowding his spot.
I hate to say but acts like this could bring some good (I am NOT condoning this action!). The crowding issues are getting to the boiling point. Maybe the state will stand back and assess the situation and make some changes to alleviate the pressure, crowding, and frustration. They've always been about free access all season to everyone but we may have hit critical mass that calls for restrictions. Of course if they do place limitations on use that will just move the problem downriver off the management areas and into people's back yards. I think the root here is the North Alabama population has grown considerably in the past 30 years and far too many people, with money and time, want to hunt ducks. More hunters and fewer places produces hostility and that brings nail dumping nastiness etc. to the table.
In many respects it's nothing like what it was when I started in 82.
