Bee Keeping

I was cutting grass a couple of months ago and on the first round I was watching and trying to cut as close to the curb around my shrubs. I noticed several bees but thought it was just because the shrubs had blooms. The next time by I looked over and there was a huge swarm of bees gathered on my shrubs to where my shoulder should have about touched them the first time by. I don't do bees so I called a local and he and a lady came up and put on their suits. He held the sack and she raked them in it with her hands while I watched from about 50 ft away!
