Greetings BEE-Ler's ! A fella from the west coast ( the shoreline ) was telling me how the bees there tend to swarm themselves silly. I've seen it. They swarm until there's no defence against robbers. I live 30 miles inland and have normal swarming. He wanted info on an 11 inch deep frame thinking that it would provide a better brood pattern that would control the swarming. So if anyone "out there" has had any experience with these larger brood boxes I'll be scaning my puter. Peace man, Harry Sweet
