Hey bud I'm from central PA too. I've been out about two times a week for the past 2 weeks...still no activity. At least where I go on state game lands anyway.
Shoot me an e-mail,let me know where u are from, I'm from a little town called Brisbin.
Once they start gobblin, I'm out almost every mornin locating birds. Man I can't wait should be real soon.
