The LA media can not get enough of the upcoming visit to California by The Duke and Duchess of Cambridge. It is actually a fascinating itinerary. The expected red carpet galas will focus on business and promoting young British talent. Perhaps more interesting is a scheduled visit to LA's Skid Row, the city's homeless enclave. They will also attend a 'job fair' for veterans. Skid Row is more than a row. It is akin to a moderately sized neighborhood comprising 50 square blocks. I have spent some time there recently and will be reporting on the plight of LA's homeless veterans for a Radio 4 documentary next month. To the "shame" of many, some US war heroes are living in squalor. Others are barely living at all.
