There's more than one way to travel. One way, and probably the most popular, is to have a start and finish time and place, and just see what happens in between. It allows freedom, total flexibility, and a lot of fun. If you visit somewhere you like - great, stay a while. Likewise, if it's a dump, move on the next day. There is no commitment, except for following your nose.
In 2001, that's what myself and a good friend, Simon, did. We started in Frankfurt in August and finished in Cairo in December. In between we packed in eleven Eastern European countries, as well as Turkey and Israel. It was, to quietly understate it, great.
Yet ever since then, we've chosen an entirely different means of travelling: travelling on a mission.
