Golfing Bees

When we got to this call all we saw was the cabinet, closed and locked. We saw the bees going in and out of a small hole on the side, so we knew they were in there. When we opened it we saw a very large swarm.  I wonder if they picked this cabinet because they golf? We had to move all the clubs out so we could get to the bees.  There were so many of them that when we moved the clubs many of the bees fell to the floor.  Once we had them in the nuc we placed it outside near the hole they were using.  As you can see in the last picture they are heading to the queen.
