Where do you put this on your resume?

When I was younger I used to spend a lot of time playing role playing games like Dungeons & Dragons or Traveler. In these games your character would almost always have a job description of "Adventurer". You would always be on some sort of quest for riches, fame and glory.
As a kid, this seemed to be a perfectly normal profession and one that anyone would want, but what happened to that? Surely there is adventure to be had in the world today. What would the life of a modern adventurer look like? How would you explain that to a future employer? Would you ever need to explain?
