This is my second season, and I feel like I'm getting a bit better every time I go out.  I have never shot a turkey yet, but I am determined.  
Here's what happened this morning.  I get to a good spot and set up two decoys (hen and jake).  Around 5:50am a gobbler starts gobbling from a tree about 90 yards off, real close.  I'm hunting in Maryland, btw (near Frederick).  
I sit tight, I don't throw a tree help, I throw a couple of soft clucks.  He must have gobbled 40 times, right up till about 630am.  Then he pitches down.  I throw a louder yelp as soon as he's on the ground.  
Long story short, he wandered off in a direction that he consistently moves in, although I didn't hear any hens.  He also would have had to walk down a narrow tree-lined trail to get to where I was sitting.   Never saw him get close, and heard his calls grow further distant as he moved in the other direction.
What did I do wrong?  He was so close!  So frustrating.....!! Thanks for any advice.
