It's a pretty steadfast rule in Physics that heat rises, no?
If I am 98deg in my stand.....and the ambient air temp is 30deg.......there's a "fair" chance my thermal is rising above the level of the deer's noses in my immediate area.
HOW can applying the knowledge of this law NOT help me?
I agree with Jeff here .... seems easy to me ...
