Last time I ran into bees in a pipe it was some wasps or something, flying into and out of a truck axle off of a 5 ton that was sticking up out of the sand in the demo range at Combat Engineer school at Camp Lejeune. They were pestering students who were doing things that required their full attention to do safely.
I blew the wasps into oblivion with a couple of pounds of C-4.
McGiver.....is that you?
