Just do a lot of walking and sitting til you find a good flock of toms. When you run into a flock of mature toms, hunt there often, you'll see em again. Don't hunt where you see a flock of hens or a flock of jakes, mature toms travel together in the fall and they compete with other flocks for food. You don't want hens around you in the fall, its a waste of time. When you find a flock of mature gobblers and get them patterned pretty well, set up in the area and gobbler yelp just a little bit to them til they get curious enough to check you out. Sometimes you won't even have to call, just wait for them to feed towards you and pick one out. Don't do any hen calls, and don't expect to hear any gobbling in the morning. They gobble sometimes, but not much at all. I would just go to an area where I have had good success in the spring and walk and sit a lot, watch to see if any flocks of toms show up.
