A young entrepreneur has finally been able to set his California Dreaming in motion as he jumped on board his double decker bus for a once-in-a-lifetime adventure.

Nathan Jenson, 24, set off from California, Yarmouth, on Saturday to make a 3,000 mile journey to California, America, in a London bus to raise money for the East Anglian Air Ambulance.

Mr Jenson and his six travelling companions said a final farewell to friends and family before heading down the coast to Southampton, where the bus will be shipped to New York. The team will then drive the bus along Interstate 80 to California - a journey which, with an average speed of 42 miles an hour, could take up to four weeks.

Mr Jenson, 24, said: “I've always wanted to do something like this, I'm excited that I've finally got the chance. My love of transport isn't something new - I bought a Green Goddess fire engine when I was 17 and my mum went mad. Since then I've owned and limousine and an ambulance.”

The bus, a Routemaster 2347, served on the streets of London for 43 years and travelled more than a million miles before Mr Jenson bought it from a friend nine months ago.

He is planning to auction the bus in America, but said that he is hoping to buy another when he gets back home. “I don't think I could bear to be without one. Maybe I could live on it!” he said.
