It's an irritating reality that many places and events defy description. Angkor Wat and Machu Picchu, for instance, seem to demand silence, like a love affair you can never talk about. For a while after, you fumble for words, trying vainly to assemble a private narrative, an explanation, a comfortable way to frame where you've been and whats happened. In the end, you're just happy you were there - with your eyes open - and lived to see it.
