Preparation for the Life of a Gypsy

I've actually considered what it would be like to travel the road with nothing but my car and some essentials, as suggested in Amber's blog. Specifically, I'd like to drive around looking for empty green spaces...mainly forests and other green spaces that haven't yet been touched by developers...in order to practice my martial arts in solitude. However, there is one essential other than those listed in this post that I would make sure I always had with me: money. It would be quite necessary while I was traveling: to maintain my car; to fix the car in case something ever went wrong on my road trip...including the money for a tow truck and a hotel in case the repairs required more than a few hours; to buy more food whenever I ran out; to wash my clothes at the campus laundromats, or to buy some clothes in case any of the ones I brought were somehow damaged. Money is, unfortunately, a necessary evil...which is the primary reason one should be careful about abandoning that job he/she hates too quickly ("Quit Your Job" post). Just a thought....
