If you know you're the only ones out there, set out your decoys with a jake. If you think you've over-called, hit the gobble call a few times now and then. I have yelped and then gobbled to my own call. It may drive away a single tom, but if they know they're the big boys, they may come in looking for a fight. Make sure you have at least two hens to make it work their while. They should if anything, come out to investigate who gobbling with hens on their turf.
