While driving near downtown Minneapolis this morning, I saw what appeared to be a perfectly healthy young woman riding a bicycle in a normal fashion. On the bike were custom made racks constructed of vertical PVC pipe. Stowed in these racks were crutches, These were the type of crutches with arm clasps, not armpit pads; the sad kind of crutches you might associate with a chronic muscle disease or orthopedic problem, not a broken leg. Can anybody think of a an explanation for a crutch rack on a bicycle?
