i agree with most people on this one...
i have been hunting 20 years and ive always pissed on the ground where i was.
and i have no problem hanging out the window of a blind and letting it fall....
i have never noticed it to bother them.

Also.. for 40 years, my dad smoked Cigarettes.
him and his friends would always Chain smoke in the Blinds, and yet they always killed deer.
my dad kills 1-2 bucks every year, and has over 10 deer mounted in the 150 - 160 B/C Range.
all while he smoked in the blind... But i DO NOT Reccomend this.. (nor do i reccomend smoking anywhere)
but also, as long as i can remember, they were up high in tower blinds where you get get away with a little more.
not quite like Bow Hunting a Game Trail...

I rifle hunter, w/ a 300 Mag.. 20 feet in the air..
w/ 200 yard Senderos can get away w/ ALOT more.
