posted a funny piece about knot holes in a park latrine. The next day I was walking across a bridge in our local park. It's suspended a good 40+ feet above a ravine. The planks are narrow and not very thick and you can feel them giving under your feet. I looked down and saw that one of them had 3 knot holes through which you could easily see the ground below. Hmmmm. Maybe a little patch work in order here.
