I had my climber portion of my stand up too high and it negated an easy shot at a doe at 15 yds. Being up too high. Compensate low for deer that are on edge. Wait awhile on marginal shots. Check your boots after walking through a neighbor's yard that has a dog. this one cost me a doe two seasons ago at 20 yds (brush prevented a shot). Be ready at last light. I had ten or eleven deer come out of a thicket at last light and I nearly didn't get a shot because they were all moving soooo fast. stand as much as possible. move as little as possible. don't hunt a stand with a marginal wind. and I am sure sooo many more, but I cannot think of them right now. so many of my lessons have turned into automatics.
