Winter update

Over that past several weeks it has been relatively cold for this part of the country.  Temperatures have gotten down into the 20s (Fahrenheit) at night and often not gone above freezing during the day.  Today it was in the high 50s, and there was some definite activity around the entrance of one of the hives.  The other hive had no signs of life, so I opened it up.  Sure enough the bees were all dead.  They still had quite a bit of honey, but it wasn't near where the main bee cluster had been.  I can't remember if this was the hive with a queen or not.
