Some weeks ago I fenced off our "backyard" as it was one of the few places left with any grass. I have turned a couple of horses out there and all went well until one of them stuck a hoof through the lid of a septic tank. (I didn't know we had one there.) Amazingly she was not injured but the lid was. While I was waiting for the septic crew to remove and replace the huge concrete lid, I decided to clean out a neglected flower bed which was overgrown with mostly dead weeds and vines. I now have a disgusting case of poison ivy AND chiggers!
