Click here to send this news item to a friend Prince Charles' and the Duchess of Cornwall's eight-day tour of the US took them to New Orleans this weekend, where they saw at first hand the devastation wreaked by Hurricane Katrina.

Army officials showed the royal couple the area around the breached levee and explained details of the reconstruction effort. Later on, Camilla's easy manner was once again apparent as she chatted with young victims of the disaster.

Then it was on to California and a farmers' market in Marin County, where the heir to the throne and his wife were greeted by hundreds of supporters. Some held US and Union Jack flags and one sign even proclaimed "Charles for governor". The subject of the banner was clearly fascinated by the organic produce on display and enjoyed some in-depth chats with the farmers.

On Sunday, the royals arrived in the city of San Francisco to see the long-running wacky musical Beach Blanket Babylon, which the Queen had seen 20 years previously. For that outing Camilla chose a black jacket and bright floral skirt. The cast members are used to seeing celebrities, but producer Jo Schuman said this year's royal visit was "as big as it gets".

Earlier in the day, the Prince and his wife attended a service at a local church in the rural town of Inverness. The royal pair fly back to Britain on Tuesday after visiting a local school with Maria Shriver, née Kennedy, the wife of Governor Arnold Schwarzenegger.
