i know there have been times where you shoot your deer and watch it run away, but in the excitment don't see the specific last spot you saw the deer at...if so i suggest playing golf....i play golf and it forces you to watch the ball after hitting it all the way to exactly where it lands...it is good practice for watching things (ie hit deer, hopefully in one or two lungs) while they move until you can't see them anymore....just a thought i had while golfing this morning.....it really helps if you are a bad golfer like myself and hit them O.B therefore you really have to watch the last spot you had seen the ball in order to find it...
