I wen't hunting Saturday and had a ghost deer spook directly under my stand. I never saw it because it came in from behind me. But aparently it either saw me move my head or caught wind of me as it was going under my stand. I was about 16 feet up. My first question is... is that high enough or do I need to go higher? This is my first year using a climber so I don't know what height I need to go? Also, how will my height affect arrow trajectory? Is a 20 yard shot still a 20 yard shot? (if you know what I mean?). Thanks for the help and advice.
