If I climb higher than 15ft (say 20ft), how is this going to affect my shot placement? Now I've heard people say that you have to compensate for the angle, and I've heard people say that unless you are rediculously high, it doesn't matter. I don't have a rangfinder, nor do I have the money to buy one. I am pretty good at judging distance and do so with trees when I get up in the stand.
