People get about a gallon a week, but the black market is always there to help you out -- for a price. Speaking of the Black Market -- that was the only way to change money into Kyat (the local currency). There are no ATMs / credit card machines, and you can't change travelers checks because "Official" Exchange rate is about 1 / 200th the real (aka black market) exchange rate! (Yes that's right, the government fantasizes that the money is worth 200X more than anyone will pay!).
