water foraging

It's winter and a few days ago snow and ice covered Atlanta.  My bee activity expectations are extremely low.    The temperatures barely touched 50 °F, but with the leaves down, the afternoon sun touched the landing board.  On an old post, I showed how to make rafts using plastic straws.  However, this is the first time I caught the bees using the raft.  What can I say, I'm easily flattered and entertained.
