It is amazing how many call these birds stupid. These are some of the smartest birds in my book. They have great eyes and can sense when something is not right. I've been after a few big gobblers here in Missouri, but with high winds and lots of rain my time is up. Each time the gobbler was with a hen and that is almost impossible to get him away from her. You are right on track to roost them and set up next morning. What I do is some light clucking when they fly off the roost to let them know you the hen are in the area. I'm sure you know patience is key, but I'll be honest when a big ol tom is coming it is very hard to be everything but patient. Good Luck and get em.
