I personally absolutely hate when people set up next to my stand, but if I had a stand for every acre of property, I guess I'd just expect to have some overlap. Under the circumstances you described, I would personally perfer to find a different area altogether. But if you're stuck there, then I'd say don't worry about. Just hunt where you wish to hunt and if you end up intefering, then I agree with jetblast. First come, first served.
