Ben Franklin once counseled, "Let honesty and industry be thy constant companions, and spend one penny less than thy clear gains; then shall thy pocket begin to thrive." In the spirit of our founding father, Ego sent three willing (and excessively spirited) writers on the most frugal of journeys into the heart of Philadelphia. Their self-designated aim? To thrive, nay to prosper, on the budget of the most penniless pauper -- that is, no money at all. Their journey reveals a city ripe for even the poorest of pluckers.
