I hope you didn't sit and watch the entire video at 7 hr and 43 minutes. The camera gets zoomed in between 3 hr and 30 minutes to 5 hr and 20 minutes. The crowd in the background are all oblivious to the colony being so close. At the last of the video there are more people in the background.
Very cool though. Most times bees hang their comb down from the top. it must of taken some tricks to get the bees to build the comb up.
