Number 1 rule at our camp after anybody shoots:

Do not get out of your stand until somebody (only 1 guy) comes over to assist. Depending on stand locations, this can take up to an hour by the time the guy gets down from his stand and walks over to the shooters stand. Using a radio, the shooter directs him to the point of impact as he looks for blood. Once he is certain to where the deer went and the blood is marked, the shooter can then get down to decide howto proceed. It is very true about the woods changing once you get down. Since we have all hunted together and hung out for about 30 years, we are all more that willing to help each other out. Also, once the deer is found, you have a buddy to celebrate with!
