The guy got lucky and stumbled accross a buck bedded down no rocket science here.
Believe it or not I have seen this happen.. A couple years ago they finished taking up the railway in our province. We were driving on it in the old trcuk and decided to stop and get out for a stretch and look around at the area. Well my hunting partner got out and headed off the trail and into the woods to look , and when he broke through the woods there was an eight point buck laying there resting . It never moved it figured it must have been invisible. He shot it right there never got up How lucky can you get.
