It was one of the strangest things that have ever happened to me. I was trimming with my trusty Redmax around a few yard items when I hit a little clump of rocks. They went every which way, here and there, and before I could back off, I felt something hit me in the nose. After it hit me and I backed away from what I was trimming, I noticed that something just didn't feel right. Wanna know why? There was a rock up my nose!! Lodged in my right nostril. It was just big enough to get in by the force of the trimmer, but not small enough to just drop out. After a few seconds of work, I had the darn thing out. Man, did I feel better.
