help for a first time longbeard chaser

[dbenham]

I am usually found in the duck woods but due to the bad season, I have decided to scratch the turkey itch that has been bugging me for a couple of years.
I am lucky enough to have free access to my father-in-laws property in Miss. I have done some scouting and there are plenty of birds. After 4 hunts I have had a couple of exciting moments.
On my first hunt I was bouncing around the woods and edges of fields trying yelps and shock calls to locate a bird, but heard nothing. It was below 40 degrees that morning, does that effect how a turkey gobbles? Finally I just gave up on killing one my first day out but didn't want to leave the woods yet. While sitting there unprepared clucking and purring on a slate call, i catch a huge sillouette out of the corner of my eye. He was about 40 yards away and came in completly silent. when he was behind a tree, i started fumbling around trying to get set up and he must have heard me. he stayed behind the tree and was more patient than I was. After about 3 minuest of holding my gun up and my heart beating out of my chest, I thought he might have snuck away, when i moved to peak around the tree, he took off. Still a decent first effort i guess.
The next was yesterday. As soon as I hit the woods some crows flew over and triggered a gobble. I tried a mouth call, then a slate call, and nothing. Then I broke out the box call, and he cut me off with a gobble. From then on he was hammering me on every call. I might have been calling too much because he was hung up about 200 yards away. I couldn't go further because he was off of my property, and i would have been calling from a downhill position. I deciced to slow up my calling and wait him out, when the farmer on one of the other properties cranked up a tractor, and that was the last gobble I heard. Still, we had exchanged about 20 yelps and gobbles. For me it was very exciting.
How do ya'll handle a hung up bird?
Any tips on position and calling techniques would be helpful
