The brick wall seemed just the perfect height for a jump--possible, but with just enough risk to make it impressive. So standing there, I pumped my legs and hopped up to a standing position. But wouldn't a video be great? So again...losing balance and landing back on the sidewalk and then a hasty third attempt, without any of the fine tuning, the eyeing of distance between my body and the wall. Without listening too hard, I still hear the crack of my shin. See the flap....and through the blood, the bone.
