Just a suggestion.. but it couldn't hurt to be aggressive and mobile. Maybe make moves on them if they won't come in, especially if its the last day. Maybe forget the decoys for the last day and just try your best to get on them and get in front of them. I'm no expert, but one thing that helped me this year was trying my best to judge how far the gobble is coming from, and moving a little closer, get him to gobble, move a little closer, get him to gobble, move a little closer,repeat..until its obviously time to set up and he's pretty close. Its risky, but fun.. If they aren't gobblin much, I wish I had that figured out.. For no gobbling, I would agree with what was already said, set up on them where they are entering/exiting field. For rain, your field edge set up may produce.

Good luck, have fun
