curse of the blind

Good stuff Danes.  I've got a similar situation to you, trying to draw gobblers off the roost where I don't have permission to hunt through a field to property I do have permission to hunt.  I can get within about 75 yards of where they roost sometimes.  This morning seemed like about 200.  To top it all off, they've got to cross an old barb wire fence to get there, but there are several low spots where they can cross easily.
 
Yesterday I didn't get out till 9:30.  As soon as I set up, I saw some hens working my side of the fence.  The gobblers were sounding off just on the other side of it, about 100 yards from my post.  Eventually they went silent.  I would call softly every 10 minutes or so.  Knew I had to leave no later than 11:35.  At 11:25, for just a couple of seconds, a big red head appears out of the wheat just on the other side of the fence.  Gone.  Stayed another 10 minutes but saw or heard nothing.
 
This morning, a few gobbles off the roost, and a few gobbled at crows.  Watched a parade of hens come out of the woods, into the wheat.  At least a dozen birds.   
 
Got a few hours in the morning to try one more time, then I'm done.  This has been a very educational and exciting season for me.  I've rarely hunted turkeys in the past - once or twice a year as a teen.  Never saw or heard any.  A couple times a season with a good buddy who is a big turkey hunter when I lived in KY from '98-'01.  First time I can recall every hearing a gobbler.  Maybe three or four other times in the last 7 years.
 
But at least a couple times a week this year.  Like you, despite not connecting, I've had a great time and really enjoyed being out in the spring woods.  I've seen LOTS of deer, a couple skunks, 2 pairs of orioles.  Watched 2 pairs of geese go from nest to leading their goslings around the farm.  They are turning grey already. 

We also been real close all year.We only went out one time an never heard a bird.We are hunting community turks right now beside the house.This is the first day since a worked these 3 birds i got to go after them again.These birds receive alot of pressure but most guys try to call them to a plowed field.My been a idiot like i usally am.I told the old man the only way we're going to kill these boys is get in thicket with them.So we got there at 5:20 no need to go in early now not with all the leaves.We sat there an never made a noise so about 5:40 one starts about 50 yards in front of us.We was hunting with a fold blind up looks like a barlap sack.So about 5:50 a give them a cluck boy where we into turks hens and gobblers everywhere.I did a flydown man did they go nuts.They keep getting closer but we couldn't see a thing out of this blind.I took the corner of the blind down in the woods want quite.They must been right on top of us **** IT 2 days left good luck and be safe.

Blinds are great for bow hunting but are not needed for gun hunting and in fact may hinder you IMO. In many cases you need to be mobile and move in relation to what the particular turkey your hunting is doing and blinds and decoys do nothing but slow you down and lock you into a position that may not be where the turkey wants to go on that particular day. While the object is to call them in you have to be positioned where they are willing to go.
