Wear your Nike's and be ready to run. Any bird that gobbles more than twice will bring 3-4 hunters that won't hesitate to go right past you to get to the bird. I've run into some of the most uncouth, uneducated hunters I've ever seen up there.
As CBU posted, you'll have your best luck setting up on some sign, do some very light calling, and hope a shut-mouth one will strut by.
