but set my stands as close to their bedding areas as possible keeping the wind in mind the whole time.
Thats good advice.
I don't buy the completely nocturnal thing myself - big bucks move during light - they are just no moving in the locations that you are hunting. Get as close to the beds as you dare, stay out of the open woods and set up in thicker areas. These are the areas mature bucks may move during light.
If you convince yourself these bucks are unhuntable - they will be just that - Unhuntable. Have confidence that they will move - and set up close to there beds.
Good Luck[8D]
