Awesome. It is a fun experience.
I have a limited tag and will pick up an OTC tag as well.
Don't over call. I tend to do a 30 second call sequence roughly every 5 minutes. If birds are responding and they seem to want more calling then I increase my calling.
Don't move, they will see you. Learn to use a mouth call. Usually when I determine a tom is working his way in I get ready with my gun up and use the mouth call to keep him coming. Also, don't move because many times they will come in quiet. This is another reason that calling every 5 minutes or so tends to work for me, less movement. I swear these birds can pin point the location of a sound from an hour earlier.
