Yellow jackets will hunt you down. They know who disturbed their nest.When I was a kid, I would work for a man that had a contract to mow cemeteries. We did it with old Yazoo push mowers. It taught us to be quick on our feet because about every 100 feet was a Yellowjacket nest under a head stone. I can't remember what it paid, but probably four or five dollars a day. Big money when a candy bar was $.05.
