Bow hunting from a treestand.
#7

Practice from tree stand height, whether it's from your stand or some other platform. Also, when hanging your stands pay close attention to where any limbs may be that could get in your way when drawing back.

I try to aim a little lower than I would shooting from level ground especially if the angle is steep. I bend at the waist and when bow hunting I won't wear a coverall because that tends to inhibit my bend. When bowhunting I wear pants and a jacket to get that seperation.
