RE: Thats it- I've had it- Its time to get dirty.
Nothing is worth someone potentially getting seriously hurt....
If it were me, I'd actually put a note on my stands themselves...
Something like:
"DO NOT TAKE ORMOVE THIS STAND, I have permission to hunt this property! Any questions call999-9999"
Maybe you'll actually meet whoever is doing it - who knows - could be just a big mis-understanding.....
