Printing money, local currencies, communities and the economy - MSN Money: "Last year, two Detroit tavern owners were sitting at the bar, sampling their beverages and bemoaning the local economy -- no one in the city had cash, and when they did, they spent it in the suburbs. Then the pair hit on a solution: Print their own money.
It is, after all, perfectly legal for anyone to issue currency, as long as it doesn't look too much like a U.S. dollar. Thus was born the Detroit cheer, a local scrip accepted by a handful of city businesses, including a pizzeria, an electrician and a doggy day care center."
I think this story ends with people exchanging live pigs for baskets of apples.
