Very cold, very windy morning. Didn't hear any gobbles at first spot- sitting field where I had seen a tom strutting a week ago. About 9:00am I starting covering ground. Started hearing a couple gobbles around 10:30- all the reading I've done says they should come right in at this time, but they kept moving away from me on long flat timbered ridge. They answered a couple times then went quite. several minutes later, I'd hear them again a little further away. I tried to follow them. Not sure if I bumped them or not, but after about 1/2 hour of this, I never heard them again. In hindsight, not sure if I should've just stayed put after I was setup on ridge, even after hearing them get further away. Or if it was the correct call to try and get closer. I don't think I could've gotten around them and found them again.
