I've run across ground nests several times while bush hogging. They like to nest in and under piles of old clippings. Usually I notice them before I run over them but last month I hit a nest while I was turning the tractor around and didn't see them until it was too late. Seventeen stings in a matter of a few seconds is not a fun experience. The good news is that I'm apparently no longer allergic to the stings like I was as a child.
