This happens here every year, but rarely do I see it. This year I was home drinking beer contemplating my next move. I had just looked at some bee activity on this hive that I didn't totally understand, after 28 years.
I went down to look at the very few bees on my apple trees and thought nothing unusual.
Then I heard the noise again, a moving swarm. I was frantic to get my camera and hoped I had a battery with enough charge.
It worked out well.
