I used to climb a decent amount in high school and college, but had to cut way back once my wife and I had children. Since climbing trips became more rare, it was frustrating when I did go climbing to be so out of shape. For conditioning my forearms, for training climbing moves, and for fun, I have wanted a climbing wall for a long time. My initial vision was to have a small indoor wall, but it is tricky to locate space for this and to convince my wife that it is not going to seriously detract from the decor. So, I finally settled on trying to build an outdoor wall.
