I did the opposite this morning....
Went to a spot where I thought a gobbler should be roosted and heard nothing, waited til way after fly down time...nothing. Crossed a small creek and popped up on a knob and there he sat, still roosted at 7:30, looking me dead in the eye !
Eased over 1 step and put a tree between me and him. He didn't act too terribly alarmed but set his wings and sailed down the mountain about 150 yds........
Turkey 1...Me zero
Been doing this 38 years and still screw up at least once a year....rookie......
I have seen it work the other way though, just usually not for me
