After reading about people who travel in order to understand other cultures or generally become a better and fuller human being I might hesitate to say that I travel for the fun of it, but that is pretty much what it is.
I grew up with the Saturday movie serials, the adventure stories that Steven Spielberg drew on in fashioning the Indiana Jones stories. As a little boy with no adult supervision I assumed that was what life was going be like, but it wasn't, until I discovered travel.
It is the common sin of travel writers to self-romanticize, but the wonderful thing about travel is that, if you have done it well, you don't have to make things up. It really was an adventure. Not like Indy's perhaps, but good enough for we little boys, now grown up.
