I've been thinking about this for a while, now.....and I have a different twist that I don't know has been addressed (that "might" make your guide's outlook/ideology seem a little more sound).

I would "think" that a hunter.....hunting in an "all day sit" type situation.....runs a "risk" of having to get down and relieve himself a LOT more than the hunter who is only sitting for 5 or so hours. If your guide's trying to eliminate as much human scent in the area as he can.....he may be banking on this. I don't know too many guys who can (or will) stay in their STAND all day.

I'm also not making the assumption that human "waste" is any more discernable to the whitetail than any other animals'. I'm just making an observation.

I would also "surmise" that not every hunter is as versed/dedicated/committed to their scent regimen as the guide would like for them to be. He may demand it....and, if so, I think he's doing the right thing (again....it's YOUR money.....but HIS means of making his living). He has to put another hunter in those woods after you leave. I hope the term "it's not all about YOU" isn't too harsh.....but I think you get my jist.
