Thank you all. I took all the precautions though. Bathed in scent killing soap. Washed all clothes in scent killing detergent.Entered the blind two hours before the deer started moving. Put the blind up three weeks ago and avoided going anywhere near it until yesterday. The blind is carbon coated on the inside to hold in any smells. The only thing I can think of that was different was the flap was opened just enough to see the trail and shoot an arrow through. I'll leave all alone there until shotgun season. Time to fall back on plan B and use the tree stand up by the corn field. Thanks again.
