If you don't know where they are bedding, look for ravines and creek beds leading out of the crop fields. When you find them, look for the trails/signs of deer movement through those areas. Right inside those ravines and creeks are where the deer will stop before going to the bedding areas to make sure everything is hunky-dorry before they continue. During the evening, they do the reverse. They'll get to the edge of the fields inside the "safe zone" and wait until they are ready to head out into the field. Good Luck.
