I've gotten blasted by those bastards too many times to count. One of the worst I'd seen was when I was cutting trees. The climber lopped off a dead branch with a big colony in it. As soon as the branch started falling they whizzed out and started nailing him, then the branch hit the ground and the rest came after me.
He was stuck tied off to the trunk 20 feet in the air getting swarmed. To get away he unhooked and tried dropping, but in a panic ended up swinging, flopping and dislocating his shoulder as he tried to grab and break his fall.
I hate bees.
