Travelling is not the best way to make friends since there are too many risks. There would be some people who have better luck with making friends while traveling. Of course, making friends on the road has several merits: You get to meet a wider variety of people than if you had just joined a sport team, and since there's no competitive pressure, getting to know people can be a much more relaxed process. You also have stories of your travels to relate to people you meet along the way. However, it cannot be denied that there are many hidden risks of being swindled. In a matter of fact, the so-called friends travelling together are strangers, whom you never ever knew about. There wouldn't be that camaraderie that comes from working towards a common goal, and not to mention that a lot of the people you meet you'll probably never see again. In this case, the temporary friend could not share the everlasting relationships and contains uncontrollable risks.
