Top Rope Anchor

I was discussing the top rope anchor that I used with a friend today, and to illustrate, I drew this:


I know it's not exactly a picasso, but it shows the basic idea of my anchor. Two pieces of webbing attached to two bolts, plus one cord attached to a metal pipe. This provided three independant protection points, reducing the possibility of failure to nearly zero. However, I think in the future I'll throw a fourth piece somewhere, probably an extra webbing into one of the bolts.
