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

For years he had dreams 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 kilometers 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. Realizing 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. '
