I also think it makes no difference.Big boars that have some age on them are slick,like all trophy animals except that big bears could be 20 some years old vs what we think of deer being old and cagey at 6 or 7.
Then imagine that, that bear has survived,living around a hunting operation all those years.They often come in very late,may circle and scent check the sight and will look into the treestand to see if there is any movement.
They probably won't see you if you stay still,but they know where the stands are.Don't panic if they look there.
Big boars also may come to the thick brush on the fringes of the site and then just fade away,I guess just having a feeling something isn't right.
I don't sweat the fact that rifle hunters have been in camp.I'm sure bowhunters spook far more bears than the rifle hunters do.
