Here is a photo of the Red British-themed double decker bus, with a banner greeting Queen Elizabeth and Prince Philip. They arrived in San Diego on the Royal Yacht Britannia for their 10-day West Coast tour in 1983, which was hosted by President Ronald Reagan. The visit was dubbed 'The Scuba Tour' because of the almost constant rain, the cities included were San Diego, Palm Springs, Los Angeles, Sierra Madre, Duarte, Santa Barbara, San Francisco, Sacramento, Stanford, Palo Alto, Yosemite, and Seattle.
