Could you survive without money or resources in a new city?

Hey, don't we all dream of working as spies at some point of growing up or another? I certainly did and still love to watch all kinds of spy movies and TV shows. The one that has been really catching my attention lately is Burn Notice with the dreamy Michael Weston played by Jeffrey Donovan as a CIA agent. To be a spy and to be a successful spy is not an easy task, but I think Jeffrey Donovan is perfect for the role. Spies always need to have their wits about them and to be able to bounce back from any situation. I wonder if I were to get stuck in a city without money or resources, if I could manage? I think I would manage to survive but nowhere near as well as Michael Weston would, of course.
