rough...are they walkin by your tree? if so sounds like ya kno what needs to be done by movin it around.
if not, well, get some cover fer up there, weather its just hangin sum camo or gettin on the ground..dress like a mountain and you'll be good on the ground, if they are comin down the hill to ya then that says to me your about the same height as they are on the ground at some point anywaz..scent control of course..
