Couldn't find the buck. It appears that the shot was maybe on the bottom of the lungs, definitely some lung blood and the deer seemed to be bleeding out the mouth some. He went into a large pine plantation area with a lot of underbrush/briars. We found one more spot of blood where he crossed a road, but there are so many deer in the area we couldn't tell if the buck went out of that block or where he went. The blood stopped. We never did find a place that the deer laid down. A lot of running large tracks on the road system. I called around this morning trying to get a blood dog, but the majority of the dog hunters have quit over the last few years and the couple that might have a dog were working. Just one of those things that happen if you hunt long enough.
