I know your pain. We bought not leased, 10 acers of prime hunting land. I have seen a large 8pt on this land but it is still bow season here and he was a little far off. The next time I went to my stand I found a grunt call on the ground. I posted 25 signs that read " This land under new ownership, tresspassers shot on sight!"
Cruel I know, but I bought this land and would like to be able to hunt it.
Good luck and I hope the signs keep them out! If not my pistol surely will!!
