Stonewall,
First of all, a stand 10 feet back from a property line allows a field of fire well beyond just shooting at game on the neighboring property. It seems to be a fairly small group of people who dont grasp that. A stand set up directly on the property line and oriented so that one can only fire on the neighboring property would certainly be asking for trouble. But this one isnt, so why go off half-****ed?
Second of all, no offense to the poster, but if he is unhappy about having a stand close to his property i would imagine that his estimate of the distance from the stand to his property is probably more than 10 feet. Either way, a stand ten feet or more on the neighbors property is NOT your business, any more than you walking within ten feet of his boundary line to check out the location of the stand would be your business.
And, as I said, one can certainly do pretty much what they want on their own property, but if one is doing stuff with the intent to disrupt a neighbors hunting in an OVERT manner, you could be asking for trouble. Deer are much less skittish than folks think so i dont think that sneaking out at night and dribbling fox urine in the area is gonna have all the deer fleeing to the next county. so, if you do start doing what would probably be necessary to really drive the deer away from that spot, you are probably doing something overt that would be leaning toward hunter harassment.
And your analogy is bad. More accurately it would be an issue of if the neighbor builds a fence with a gate that opens ten feet away from your property. if you start throwing a fit about that then most folks are gonna think you are about as nutty as someone who gets their panties in a wad over a deer stand ten feet over on the next property
