Hunt, like mentioned deer will blow at a lot of things.

Had a deer blow at me 2 weeks ago hooking up my strap to my harness onto the tree. Probably 30 yards behind my stand. Just thought to myself "I get blown at while in my stand already, its pitch black and just wait till its light."

an hour later I had a buck on the ground and a few more deer still walking in on my with my dead buck less than 30 yards from them.
