Re: Got one, but w/ bad news....
How far did your arrow penetrate? Without an exit, and a high entry, blood trail would be almost nothing. Did you see how the arrow was sticking out of the deer, was it flat like when shooting from ground, or more vertical like 20ft up in a tree? If your up in the tree, and your arrow is going at a steep angle down, with 5in of penetration you would be starting to get lung. Keep looking to find your arrow, and keep searching for the deer. If its not an issue of having to let a deer lay to expire and backing out to keep from jumping him, keep searching around for any sign of the buck. Dont give up even on marginal shots, it will make you feel better knowing that you searched high and low for the buck and did what you could. It will pay off, either way.
