I would assume that it makes a difference. I always have a dip when I hunt "in a tree stand down by the river." (opposed to "in a van down by the river." -Farley) This one spot I have is on the bank of a river which actually puts my stand over water so I can spit into the river undetected, and it works out great if I have to take a leak. I usually don't dip if I'm not hunting the river spot.
