RE: Spine hit
I spined one with an arrow several years back. The sound of the arrow hitting wasn't unlike the sound of a homerun off a wood bat. I was expecting a quartering away passthrough - and for some reason that day the arrow "flew" on me - and hit where the neck meets the shoulder.
Not a drop of blood and the deer never twitched when it hit the ground. It was quite shocking really. I could see the deer's chest rise and fall still from the tree - so I put another one right in the center of the lungs before I got down - he never twitched at the shot either- but bled and bled. No doubt he wascompletly paralysed from the shot - and the second arrow killed him be hemmoraging.
Very strange hunt - I actually felt very lucky, and wasn't upset bythe shot.
