I've had those
ground dwelling yellow jackets get me while bush hogging in my front fields. I learned to watch where I cut, when coming back around, to see them. They buzz around the hole in the ground just waiting for some poor sap to come back around. Three or four of those get you and it feels like someone poured liquid fire down the arm. Yeowch! A couple of years ago, I was bush hogging in the front field and had an area where the bushes had grown out more each year. I was trying to get really close to hack it back some. While swinging around, I came face to face with my worst nightmare....Big hornet nest. I was up in some limbs and my nose was about 6" away from the hole. The sentry was buzzing his wings at me in a warning. I slowly eased the old ford into reverse and gently back out. Quietly! I had just witnessed a friend at work getting torn up by those things when he was cutting some of his trails. His head and face had knots all over it....big knots. Made an impression on me. I found another one up in the bushes the next year. Those nests are really hard to see when they are camouflaged like that.
