I had the same luck last year up here. Others hearing gobbling in other areas and I never heard one except for a jake that I was crossing the road up in front of me. Hens everywhere where I was hunting. But that jake had me change my game.. I discovered him traveling by areas where the run offs were when the snow melted. So I started setting up in areas like that and had my best season ever. But that jake that morning was the only gobble I had heard. The spring run off areas stood to reason once I had thought about it. Up in this way the green growth starts first in those areas without going into a field.. Good luck with getting one..
