You mentioned, in answer to another question, that there's a nascent banking system, which means exactly what you meant it to mean, I'm assuming. Does that mean that most things are dealt with in cash, and if so, how much cash? I remember reading an article about the U.S. sending not a briefcase or a suitcase or a brown envelope or even a truck full of cash into Iraq; it was a planeload. There's a whole question of where it all is.
What about Canada? How do we deal with it? Or do we have no need to deal with cash, and the nascent banking system works for us?
