RE: How do you decide when to .......
well if I hunt on the edge of a field Ill grab a stick and pace off 20 yds and place the stick in that spot. once im in the stand Ill have an idea about where 20 yds is. In the woods I do the same but i pick a tree or a bush. Usually when I set my stand up in the woods I do this that way I know right from the get go.and when their just so close you can hear their heartbeat,you know its right
