like perry said pete, and what you experienced, i don't care for the 'free-for-all' that happens when setting the supers out away from the hives. it is a total frenzy, and many bees lose their lives. i just don't do it. and most of the time this sets off and results in further robbing of all of the hives one has in a yard if done too near. it's not worth the risk. in addition, i don't like to try and chase bees, wasps, hornets off to bring the supers in after being cleaned up. also for me, the risk of a bear visit, is not worth it.
