I'm glad yo had a chance to catch one but for some reason I can't access the picture.
I had a customer the other day telling me about a swarm that had rested on a tree branch in his back yard for a few days. About the second or third day they dispersed and the air was full of buzzing bees as they were heading to their new location.
I told him if that were to ever happen again to stand there and enjoy it, a true marvel of nature. Man, he looked at me like I just got out of the loony bin! :-D
