As the other poster already stated, you will tend to discover over time that 90% of your shots come from within 20 yards or so. I can only recall a few hunts where I shot in excess of 20 yards. Most often the deer come right at you if your stand is setup correctly. I'm dead-on from 0-25 and pretty good groupings from 25-30 or so, but concentrate most of my shooting from 15-20 yards out.

As for equipment, spend your hard earned money on a good bow, good arrows, good broadheads and a good stand (with full body safetly harness). These are the keys to success. You could basically go hunting with this equipment alone and just wear jeans and sneakers. I will tell you this...my success in hunting did not come about until I was confident I had a good bow, practiced A LOT and purchased a rock solid stand and used a full body harness. Being up high is a nervous situation, but it's easy to forget the height as long as you have confidence in your stand and safety harness. With my safety harness securely fastened, it sometimes feels I am shooting from the ground as I don't care how high up I am because I know I am secured! Good luck.
