Videos I have seen are just not real world hunting and that's how deer and waterfowl videos tend to be. One of the best tips I read was when scouting flag down a jogger/walker and ask them if they seen a turkey this morning. Works but they tend to be around private property. I have been to waterfowl seminars before and not been impressed since I have been on the public dirt most of the time and can tell they have not, which causes me not to trust other seminars because their world to mine is night and day most likely. Most are just a live commercial as well to buy something instead of making hunters succeed.
