WOW! I just can't believe that other another hunter would steal someone else's blind or stand? I had a climber stand stole about 20 years ago, I spent 20 minutes in the dark looking for the tree thinking I was in the wrong spot until I found the climber marks on the tree.
Good luck finding the culprit that stole your blind, You can put a few lumps on his head for me! Keep your chin up! It's a shame that a few bad apples can ruin the name of so many honest and law abiding hunters.
