     Nick Campbell sat at the side of the road and wondered what to do next.He looked at the secondhand Harley Davidson he'd bought from a backstreet garage back home in Miami at the beginning of his trip six weeks before.

     For years he had dreamt of crossing the United States from east to west by motorbike and he'd finally decided that it was now or never.He'd given up his job,sold his car and set off for the journey of his

dreams.He'd been lucky,or so he thought,to find this old Harley Davidson and had bought it for a very

reasonable price-it had cost him just $600.But five kilometres from Atlanta,he had run out of luck.The

motorbike had broken down.

     He pushed the bike into town and found a garage.The young mechanic told him to leave the bike

overnight and come back the next day.The following morning,to his surprise,the man asked if the bike was for sale.'Certainly not,' he replied,paid his bill and hit the road.

     When he got to Kansas the old machine ran out of steam again.This time Nick thought about selling it

and buying something more reliable,but decided to carry on.When the bike was going well,he loved it.

     However,in Denver,Colorado the bike broke down again so he decided to take it to a garage and offer it for sale.The mechanic told him to come back in the morning.

     The next day,to his amazement,the man offered him $2,000.Realising the man must be soft in the head,but clearly not short of money,Nick asked for $3,000.The man agreed and they signed the papers.Then

the mechanic started laughing.In fact it was several minutes before he could speak and when he could he

said,"That's the worst deal you'll ever make,boy."

     He removed the seat.On the underside was the inscription (铭文):

     'To Elvis,love James Dean.'
