back in the day 100 yds off the fence was the rule of thumb..not so much these days..

Back in my day my favorite blind was on the fence line with an adjoining neighbor at a cross fence of ours. Perfect spot with three lanes to watch from the fork of my tree.

Ill agree with navs comment.. I see it every time I go to our lease... If the 200 acres one side probably bout 70-80 acres is pretty open.. Has a few small cedars here and there but that's it... We always see deer out there and they are just hanging out, eating,..etc.. So yes I agree deer can like open areas as much as cover

I will say this to the op.. I don't like the setup that your neighbor has.. I'm sorry you are dealing with it.. I've got a neighbor that has a feeder bout 40 yards off our fence at most and his blind faces the feeder so that means it faces our fence!.. When he shoots there is a pretty good chance the bullet may cross over... My brother actually had to move his hunting area from away from there after having setup a blind the year before... The new neighbor rudley setup his setup like I described.. Our side and his side are the same cover and terrain so I'm not sure why he feels he needed to do this... Pisses us off!!..

Had this happen a few years ago with blind about 10 yards from our fence line. Their lease had been pretty well cleared of brush with oak trees left. They had a feeder about 40 yards from fence 100 yards from their blind. I just parked my truck on road next to fence 40 yards from feeder. They moved feeder and blind to other side of their lease. Our pasture is thick and good bedding area. What chapped my back side was they had windows facing our land. I sure some nimrod that didn't know any better.

I'd say it depends....if basically all his property is pasture and he is setting up stands all along the fence line and leasing it out to hunters then yes it would bother me...or if the guy only owns 50 acres of pasture and sets this up and proceeds to take five deer from the stand, two nice bucks etc...then yep it would bother me but it the guy was hunting it himself and only taking a buck and maybe a doe then nope it wouldn't bother me.
