That's the coolest thing I've seen in awhile. You are going to have to trade that climber in for a 2 seater ladder stand real soon! Then you are just going to have to suck it up and let him take the first shot, then you can take a back up shot if need be, but from what I see so far there won't be any need for a back up shot. I bet if he could pull about 35-40 pounds he'd be killing deer already?
That's gotta be the greatest thing to see for a father. Good for you and your one lucky daddy!
