After a while, my boat driver thought I was insane. We started before the sunrise and kept going, and going, and going, and going... he kept giving me the international head movement for "we really should be returning for a spot of tea," but I kept motioning him further up the river. To me, the river got most interesting when we saw no more people, except for the occasional fisherman that still had remote hut for his family along the river. I had plenty of battery power, amazing music on my iPod, a full array of snacks, a ton of drinks, and nothing to do for the rest of the day and night... so I was perfectly content just going until our gas tank reached 50%. And that took a long time... and who would want to stop with views like this around every other turn?
