The Great Wall in China is about two hours outside downtown Beijing. The best way to get there is to hire a private driver. The cars are nicer than the cabs, very inexpensive (roughly $40 USD gets you a driver all day) and you have a better experience than a tour bus. But private drivers are less likely to speak English than a bus driver. In fact this was true in most of China - very little English spoken. And I do not speak any Mandarin. Which really isn't a problem, you simply have someone like the front desk at your hotel write out - in Chinese - directions to where you want to go on a slip of paper you hand to your cab or driver. But this doesn't really cover you when about one hour into a two hour trip you have to pee. And have no way to communicate this information to your driver. Well, unless your artistic ability is equal to mine, and you are capable of drawing a stick figure going pee. Showing this to your driver is bound to produce both laughter and a stop soon where you can have a brief biological break. Really quite funny.
