This subject can draw some debate. I am a big coffee drinker and I use a big gatorade bottle myself when in a treestand. When on the ground I dig a hole in the earth and create my own personal little kiddie pool and proceed to cover up.
Some people claim that deer cannot tell the diff between human pee and pee from other animals so they let loose on the yellow stuff everywhere.
Some people claim that deer's noses are so keen they can pick up the pheromones within the urine and determine that the urine was from a predator. Some hunters change there diet prior to hunting to get around this. Just pee in a bottle and continue eating what you want...right. Why take chances. A little preperation can go a long ways. I do hold off on garlic, onions, jerky because that comes right out your pores.
