I found out a little secret get the hens really really fired up on the roost with some exited hens on a slate and the hens will come to see who is there and the toms will follow the hens. The toms are really henned up right now. We've got lot's of gobbles off of a hoot tube by H.S. Strut. They've been gobbling up north way before dawn (around 5:15) and that will give you time to get close before sun up. Good Luck in MO.
