My dad ran into a hornet nest in a bush with the lawn tractor. He tried to drive away from them as fast as he could before he realized that hornets are A LOT FASTER than a lawn tractor!!!
He finally left the mower for the hornets.
I think that bees are a little like dogs...if they attack a human for no reason, its probably best to put them down. I try to remember that these are thousands of sometimes angry stinging insects and not happy-dream candy-fluff fairies who only wish us well...
Sometimes they gotta go.
