thats a bummer. but thats why we go back. what I do is measure out diff. yardages. 20, 25, 30. and then I pace off with a normal pace. when I get to the woods and find a spot I try to pace off to I find a tree to my liking. or if I find a tree I pace off those yardages and hang a ribbon to give me an idea of my yardage. hope this helps ya. good luck to ya. keep up with it and dont give up your time will come and youll appreciate it more
