I was sitting on a rock in a 3pt belay stance (legs straight feet on the ground). A small rock struck me square on the knee. I screamed like a little girl scared I had broken my knee cap. It was just bruised. First aid kit, bandage and wrapped it. Finally on the route, I had to use my knees in the Chimney, and had to struggle hard not to push my bruised knee into the prickley granite.
I seconded this behind my partner, who led all the way up. This is a real proof that you can do more than you think you can, especially if you believe in yourself. I looked at it, and didn't know that this was rated as very difficult climb (especially for leaders). I just wedged myself in there using my but back and knees. Maybe it was easier for me since I am a 200lb widebody. Glad I was on second since I fell near the top of the chimney.
