1. The deer or kind of deer you after will walk by this tree during daylight hours.
2. You study the terrain and have a great understanding of how the thermals and winds will work in the spot you want to hang the stand, then you consider how you aregoing to get in and out without letting every deer that passes by here knowyour invading their travel area.
3.The best possible cover and sun considerations.

Sometimes a natural ground blind is your best option when the "right" tree isnt there at the spot that you know deer are passing by.
