Innie Minnie Miney Moe! That tree!
Actually, good info. In a nutshell, I attempt study the deer movement, and place my treestands accordingly. Certain stands seem to be better than others at different times of the year, depending on factors of the rut, food sources, and summer/fall/winter patterns, and of course hunting weapon. My stands are setup as Gun or Bow, but normally not both. Lots of pre-season scouting. Like was said earlier, study aerials. It makes a difference when you aren't able to scout it in person.
