If the rut is in full swing and you are going in without any previous knowledge, look for rubs and a scrapes. Try to determine where the deer are bedding and where they are traveling to. Set up along the trail(s) watching the wind and you should see deer. During the rut if you can find where the does are a lot of the times the bucks will be there. After the rut if you can find a plentiful food source near where the deer are bedding, that is where the bucks will come to.
