My sweet bride of 29 years suffered from Multiple Sclerosis and was, in the several years before she died, required to use a walker. The Commando suggests racing stripes as an appropriate decoration. My sainted wife had a Bermuda bicycle bell mounted on one side of hers and a brass horn with a black rubber ball attached on the other. In the middle, she had mounted a device, intended for bicyclists, which supposedly measured wind speed and provided a read-out on a black-faced dial with white numbers that went up to sixty miles per hour.
