Somehow I managed to contract tendonitis in my right knee. Depending on the size of the boulders and the slippery nature of the rocks, this could be really painful. I fished the South Holston, the Middle Prong Little River and the Clinch. It hurts! I finally listened to my wife and wore a wrap, similar to a wrap for tennis elbow, and it really helped. It's tough getting old (er).
