Busy Bees

When I got home from work today around 4:45, the TBH bees were going crazy! It looked almost swarm-like, but I noticed that as many bees were going into the hive as coming out, which made me feel better. I went to the grocery store, and when I returned, things had really slowed down--just a few bees going in and out. I couldn't find a swarm in any of the trees nearby, and when I looked through the viewing window, it was just as full of bees as ever.
