I cannot authoritatively provide a solid answer ... but I can give you my experiences. This one is typical ... scouting last season about Thanksgiving, I came across a spot in an area of thinned, 20 year old pines where 4 heavily used trails came into one. Long story short .... wind direction became advantageous I slipped in there 3 days in a row. Saw deer every day. And thord day got a clear shot at a heavy horned, heavy bodied 8 pt. Put him in the pot.

I think the key , as already stated is getting in and out more or less undetected. Which is a tough thing to do in most cases. I have been known to approach by walking in a shallow creek, coming in only from down wind, sitting all day, etc. to mimimize stinking up a place walking in and out.
