Tell him he better bring lots of Ziploc bags to use as a restroom or they will smell it. Better yet, tell him he has to hold it in till you are done hunting, then slip some bran in his chili!
Well, I suppose there’s always a “possibility” it can.
However, all the public land I go to has hikers, fishermen, campers, and hunters about 9 months of the year. That means campfires. Add to that most everyone uses a wood stove (here at elevation in Colorado) for supplemental heat, and there is smoke 12 months a year.
Now thick wildfire smoke will move them. Heck, I get out of it if I can too.....so there’s that.
For me it is way down the list of things to worry about.
