On the other end of the spectrum, I called like crazy at a gobbler who gobble like crazy right back at me, but he would never come in.

So I gave him the silent treatment and 20 minutes later he gobbled about 100 yards closer, but out of site. I did a soft yelp and he spotted my decoy and came right in. Too bad my trigger man missed him clean, he ran off lookin' back at us with full functionality of his head and neck.
