archbishop,
Very good point. A wounded deer will run for miles if it is chased. And you must track it for more than an hour if you can not find it. I have found whether bow hunting or gun hunting that if you know you hit the animal and you found blood, sit and wait for 30 to 45 minutes. This way the animal will not be pressured to run and if it is a good shot you most likely will find it within 100 yards. But if not, always track it until it gets to dark to see anything. Even if it means crawling on the ground to find blood drops. A good hunter has respect for the animals he hunts and you owe it to the animal to finish it and bring it home.
