RE: Disgusted with myself
Greg - I'd say dead deer. One would think that, with a quartering shot, you probably at least clipped some liver, which will be his demise. You didn't push him at all, so I'd think he'll bed down within 200 yards - and it'll be Game Over.
Good luck buddy. I been there man. I know how it feels. There's nothing that anybody here is gonna say that's going to change the way you feel, or unlock some kind of a magic clue. You'll just have to give it a few hours, then get back out there and see what the if there's a pot of gold at the end of the rainbow.
For what it's worth, I'd say you've got a buck down. But then again, opinions are like buttholes - everybody's got one.
