i dont think i spine shot it, judging from the anatomy site. I hit too low, and maybe at a somewhat downward angle. I dug around in the hole but couldnt find my broadhead or anything hard really, all internals were intact when i gutted it except where my second shot went thru. heres where i hit the deer..... http://f1.pg.photos.yahoo.com/ph/woo...ot.jpg&.view=t Looks like a maybe got that artery or vein or whatever otherwise i dunno, it did not hit the spine from what i could tell.
