Was doing some yard work at my sister's place and had no idea there was an in ground bees nest there until I started mowing over the top of it. Darn yellow jackets came out of the ground after me. They chased me for a good distance before they backed off. Guess I got away lucky with about 12 stings. I was always very allergic to honey bees as a kid, always running around barefoot and stepping on them, but these weren't as bad as I thought they'd be. Not fun mind you. I've got some swollen red bumps on my arms and legs that itch like crazy but nothing too bad. Guess it could have been much worse, especially if a kid or dog stumbled across them. I'd never heard of bees nesting in the ground before. Now I get to try and get rid of them somehow.
