The landowner at one of my locations plans to replace a pasture fence near the hives this summer. I have about a dozen hives there, the closest row being about 30 feet from the fence. He will be using tractors and other equipment so there will be some noise and banging around, and he is concerned about getting stung. I'd like to hear from people who have had experience closing their hives for the day -- what worked as far as keeping the bees cool enough to stay alive.
