Once again, as soon as I arrive at the hive, the Heavens Opened, and Lo! I was Sore Annoyed.
The Master Plan (hah!) had been to have another crack at inserting a board with bee escapes to clear the top super of bees prior to taking the honey in a couple of days.
The best I could do was open the hive, drown a few bees in the downpour, realise that the cells are not in any case fully capped, close it all up and scarper. It was so wet that there was no point trying a full hive inspection.
Rain Man. That's me. There were 75,937 bees.
