In the morning，Johnson set off from his home in California．It was the start of his vacation，and he was going to visit friends at Las Vegas．Then he hoped to go fishing in Lake Mead，40 kms from Las Vegas．

Johnson's troubles started while he was driving happily across the Mojave Desert．His car broke down and he tried to repair it．But be failed．He telephoned a workshop to ask it to send a tow truck（拖車）to pull the car away and repair it．

When waiting for the tow truck he fell asleep．while he was sleeping，a tow truck arrived from San Pedro（the nearest town） and pulled his car away．Later on，Johnson woke up and thought that somebody had stolen（偷） his car．Very reluctantly, he started to walk back towards San Pedro but a police car stopped him to find out why he was walking in the desert．

    Johnson looked like a man wanted（被通緝） in California for robbery（搶劫），so the police kept him at San Pedro for the night．The next day，Johnson’s friends came from California．They proved（證明） that Johnson was a harmless salesman，so they let him go．
