One big plus to treestands is that your scent is above the deer generally speaking so you have that much better of a chance of not being busted. Also if your in a good tree with lots of cover generally speaking you are less likeing to get busted moveing around.
I have heard others say the same thing about scent. I always thought the higher up you are, the more the wind gets you and spreads your scent further and faster. Why doesn't a popup blind contain your scent better since it is lower and enclosed?
