Swarm in Canton - a missed opportunity!

I got a call yesterday that there was a swarm at an industrial complex East of downtown Canton. The lady who called was very nice, and said that the bees were on a wall. She called about 1pm. Unfortunately I had a 2pm meeting I couldn't get out of, so I told her I would be down there between 3 and 4 to get the bees. Here's a pic she sent me of the swarm:

That's a big swarm! Unfortunately, she texted me about 45 minutes later to let me know the bees had left. I would have missed them even if I had left right when she called. Oh well... better luck next time.
