if it is a doe and it is getting late at night, i will most likely shoot them in the neck so i dont have to track them. as long as you hit the esophagus they will drop right in their tracks (aim right below the white patch on their neck). my dad and i shot two does last year like that and both dropped right over. If it is a large buck, you might not want to shoot in the neck for fear of messing up cape if you are gonna mount though.
