A few years ago I remember seeing an online video about a really giant swarm high in the trees. They drove a pickup truck under it. In the bed of the truck they placed multiple single deep boxes, each with frames and a new caged queen. They got a rope over the branch and gave it a few yanks and the mass fell into the pickup bed. They ended up with a dozen or more colonies as I recall. It was an incredible video and would really like to see it again, if anyone remembers it and has a link.
