Since the guy "has taken the biggest deer on the farm so far", he's going to be "pissed", when you take "his favorite" tree stand down, he obviously has developed an emotional attachment for the area.

When you take the tree stand down, you may in essence be burning your Dad's barn down ... if ya catch my drift?

With all due respect ... you and/or your dad are going to have to grow some "cojohnes"!
Go visit the guy and congratulate him on his "big buck"! Ask to see it, and ask him to tell you the deer story. At least get to know the guy ... most of your frustration may evaporate, who knows?

A lot of the posts were amusing and/or funny ... take a picture of your tree stand and let us see it.
Keep us posted ...
