What seems to work for us is using a group of guys and everyone basically goes a different direction the first day. Then the ones that find the best sign take a few more people with them the next day. The group gets on the trails and narrows it down and puts them to bed that night. Next morning everybody encircles where the herd was put to bed and everyone works their way in doing a mix of drive and still hunt towards the area that is easiest to pack out of. The next day, guys move over to the next area that had the best sign.
