On my resume, I fill the couple of years before I started grad school by saying that I was traveling, doing research in my field of interest (Regional Econometrics) while looking for a grad school. That I was working my way around the country, that I would stop and work for a while whenever I needed the money, or found a good opportunity. That I had initiative and was resourceful.
This also allowed me to avoid mentioning that I was working my way around the country for two years as a stripper.

Seriously, I don't know your age, but it is not at all uncommon for young people to take a hiatus from work, just to travel.
