more than anything else be persistent. Your into birds, so your already got a big part of fall hunting whipped. Just keep talking to them and they may come on any given set up. Some days they want company some not. One thing I have found true for fall hunting, it is really really hard to turn birds away from the way they are headed. You can get them to veer a little to the side for a look, but they will rarely make a radical turn, they will answer and try to drag you along with them. You may have to bust them for your best chance. If you decide to bust them (especially old gobbler groups) do it at dark and return next daylight. If you can find where they are headed to feed then wait there for them. If food is everywhere, as it is here this year, with a big mast crop it get's real hard to pattern birds. In those cases get tight on the roost and be the first bird of the morning to call and call hard and aggressive, with long course yelps and maybe a gobble. That way you may persuade the dominate bird to fly down your way and the rest will follow.
