In my area of northeast Ohio, we usually can't get them to gobble in the evening.But in the morning we go into the woods really early and get in good listening spots and they usually gobble on thier own. An owl call will get them going if nothing is working usually. Another tactic we use is to get in the woods really early and set up where we know they are roosting. Like as close as 30 yards from the exact tree. I have walked under sleeping gobblers using this tactic, and they never know you are thier. Usually it works best with someone else calling from behind you about 80 to 100 yards away. They will drop down out of thier tree right into your lap even in they have hens with them. Just where some real good camo.
