I was dirty, smelly, hungry and somewhere beneath all that, suntanned. It was the end of an Inter-Rail holiday. My body couldn’t take any more punishment. My mind couldn’t deal with any more foreign timetables, currencies or languages. " Never again, "I said, as I stepped onto home ground. I said exactly the same thing the following year. And the next. All I had to do was buy one train ticket and because I was under twentyfive years old, I could spend a whole month going anywhere I wanted in Europe. Ordinary beds are never the same once you’ve learnt to sleep in the corridor of a train, the thythm rocking you into a deep sleep. Carrying all your possessions on your back in a rucksack makes you have a very basic approach to travel, and encourages incredible wastefulness that can lead to buming socks that have become too anti-social, and getting rid of books when finished. On the other hand, this way of looking at life is entirely in the spirit of Inter-Rail, for common sense and reasoning can be thrown out of the window along with the paperback book and the socks. All it takes to achieve this carefree attitude is one of those tickets in your hand. Any system that enables young people to travel through countries at a rate of more than once a day must be pretty special. On that first trip, my friends and I were at first unaware of the possibilities of this type of train ticket, thinking it was just an inexpensive way of getting to and from our chosen camp site in southern France. But the idea of non-stop travel proved too tempting, for there was always just one more country over the border, always that little bit further to go. And what did the extra miles cost us Nothing. We were not completely uninterested in culture. But this was a first holiday without parents, as it was for most other Inter-Railers, and in organizing our own timetable we left out everything except the most immediately available sights. This was the chance to escape the guided tour, an opportunity to do something different. I took great pride in the fact that, in many places, all I could be bothered to see was the view from the station. We were just there to get by, and to have a good time doing so. In this we were no different from most of the other Inter-Railers with whom we shared corridor floors, food and water, money and music. The excitement of travel comes from the sudden reality of somewhere that was previously just a name. It is as if the city in which you arrive never actually existed until the train pulls in at the station and you are able to see it with your own tired eyes for the first time.
