Ok heres one for all you experts....

Heres the situation, i got a flock of turkeys within a 100 yards, lots of cover for me and i can get a clear shot if they come anywhere straight on. Only problem is i got a samll river between me and them, maybe 20 to 30 feet wide. Will a gobbler fly across the river for a hen, or should i throw a jake or another gobbler at him??? This is a real world situation folks and im at a loss as to wheat to do? The turks have set up camp on some private ground across the creek, but i have public access on the other so let me have it yall!!!????
