There’s a shop in Monterey, and one in Carmel-by-the-Sea too, called ‘Mad Dogs and Englishmen’, a reference to an old saying and/or an old song. They rent electric bicycles that include provision for your canine companion, whether it be via a basket as below or with its very own sidecar. I think that it is unutterably spiffy, and hope to at least see a couple of pups in sidecars before I leave the area.
