I don't know if you noticed in the photo above, but Terry's ladder is resting on...air.
He was at his cousin's new house yesterday scraping some wallpaper backing off the high, high wall above their staircase. One side of the ladder was on the ground of course, and the other, well, was just against the wall. It seemed dangerous but perhaps if I knew anything about physics, I could tell you how this worked. But it did work, safely, and they got the wallpaper backing down. Yay for Terry!
