I'll post some pics later.  My dad and I doubled up this morning.  They were vocal in the trees, quiet for about 10 minutes on the ground, and then started up again.  We saw about 20 birds, 5 for sure longbeards.  It rained lightly while we were there and opened up as we were getting back to the truck.  We had them down at 6:15.  Great morning with birds all around us.
