Last year while hunting a nice buck slipped in behind me and stopped a mere 10yds directly in front of my tree facing away from me. I normally climb 25-30 ft so he was essientally straight down. New to bow hunting and unsure of where to place the shot,I passed hoping he would move farther out to another clearingfor a better shot, which he didnt. What Im wondering is that is there a good shot to take in this situation?
