I am running bee barn style hives based on Vino Farms work. (system, philosophy I don't know what to call it go see the videos.). And I am loving it. Much easier to deal with my brood box. Anyway I needed a landing board that I could attach to the front of my bee barns.  This simple design screws onto the front of the hive and makes it easier to observe the ladies coming and going so I can see what they are carrying etc.  It is at a slight angle to drain away from the hive when it gets rained on.
