This reader account of the Rally4Sanity jumped out from the many we received:
We were about a third of the way back, and part of the pre-rally entertainment was watching people trying to climb the trees near the American History Museum.
One young woman had considerable trouble climbing, despite standing on outstretched hands. It was still too far to reach the lowest branch.
All of the sudden, somebody passed over something that extended the reach of those below and gave her the extra boost she needed: his prosthetic leg. Standing on a prosthetic leg held high above the head of one of the people below, she was able to make it up.
