I know how you feel. We tracked one on Friday night for 300 yards with a strong blood trail. That deer couldn't of had any blood left. Then the trail stopped, nothing. Saturday we looked for two hours walking a grid in every direction, still nothing. Sometimes it just cannot be explained. So now we hope the buzzards will give us the rest of the story later today or tomorrow.
