We had a similar scenario a number of years ago. I put some snow fence temporarily around my hives several days ahead. This kept the bees flying straight up and down to to hives( and curious on lookers at a safe distance). Our reception/picnic area was only 25 feet away. We had no problems with the bees. *** Kate Henderson Sheepy Valley Farm [log in to unmask] www.sheepyvalley.com :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: -- Visit www.honeybeeworld.com/BEE-L for rules, FAQ and other info --- ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
