re: Had a public land turkey make a fool of me...what did I do wrong?

If he gobbled 70 yards away, I wouldn't have ever made another sound besides scratching in the leaves and maybe a couple purrs. Don't ever put your decoys right beside you. That is a sure way to get busted. If anything you should have put your decoy right where you were standing when he first gobbled and eased back about 15-20 yards and set down. Also, if you were just running a hen decoy, chances are, even if he did see it, he wasn't going to come in. I have had many birds, when I used to only put out a hen, that would see the decoy and strut and gobble back and forth for a very long time and never budge. However, this early in the season, if there is a jake decoy with her, its usually game on. Late in the season a single hen will work. You know the area he is in now and slip back out there set up and kill him.
