slicendice some may be playing high & mighty, but the point they are trying to make is that you should have let him walk rather than taking the shot you took. I do not doubt that you got lucky and hit the heart on a shot like that once, heck I spined a doe and dropped her like a ton of lead bricks, but you can bet your sweet bippy I would never try for the spine. We all make mistakes and learn from them, you got lucky the first time you tried this shot and as a result you figured if it worked before it will work again. The results have proven that this was a low percentage shot.
I followed his tracks to the last place I saw him, but didn' t find any blood. I did find some clear liquid splattered here and there and a chunk of something. I' m not sure what the chunk was, but it looked like lung.
This to me does not sound real good, if you saw no blood and the arrow was a pass through at that angle you would have had blood considering the exit was almost right out the bottom of the deer.
