Cayugad, great Ideer! I never heard that before. It seems we track someones deer every year, I have about 12 guys in camp and a lot don't spend the time shooting they should. We find where last shot by looking for hair and hair color, tells us where hit. Rhe try spotting a spot or so, the put out a strip of cloth at the last spot we saw a ytrack, blood, whatever. I always try and spot a turned up leaf patch from a dragging leg, or up around belly hieght look for a smear of blood on weeds. I also use scent as if a deer is gut shot, you can sometimes smell that green stuff leaking out of them. We have tried a couple of those lights that use UV and not had much luck. AND WE ALWAYS make the shooter stay out no matter what the conditions are, some will let others do the work.
