To hitch-hike successfully in any country you must be able to do two things: attract attention and at the same time convince the driver at a glance that you do not intend to rob or murder him. To fulfill the first requirement you must have some mark to distinguish you at once from all other hikers. A serviceman, for instance, should wear his uniform, and a student his red scarf. In a foreign country an unmistakable indication of your own nationality will also arrest a driver’s attention.
When I hitch-hiked 9, 500 miles across the United States and back recently I wore a well-tailored suit, a bowler hat and a trench coat, and carried a pencil-thin rolled black umbrella. My suitcase was decorated with British flags. Having plenty of luggage, moreover, I was not likely to be suspected of being a dangerous lunatic(精神病患者). I then had to get across to the driver the idea that I was a real traveler, and needed to get somewhere cheaply.
But even with careful preparation, you must not assume that the task will be easy. You should be prepared to wait a little, for there are drivers who confess to a fierce prejudice against, (not to say hatred of)hitch-hikers, and would no more pick up a hiker than march from Aldermaston to London. In America, my average wait is half an hour, and my longest is two hours, but I have heard of people waiting all day: they probably took less pains to make themselves easy to notice.
