Hey Jeff you could reverse your tactics and fish first light until 11 or so and then see if you could call them in later in the day. Or If you can fish a property that you can also hunt it can be pretty effective if you crow call or hen call for locator call once in awhile and load up in crappie or whatever between setups. The hens will wonder off to their nests by then and the gobblers may be more receptive. Just my two cents. I got a buddy I've been on several succesful bass boat hunts with down in Ky on their reservoir wma's. Your awful far north too, it has just been getting good down here now along the Ohio. Hang in there it'll come to ya.
