1. Internet. Hah! By the way, there are no roads here.
2. Red Bull. I think we are even beyond Coca-Cola, but there's plenty of Red Bull around. Ew.
3. Altitude. Indeed, we ran right into it! I think we're at 12-13k feet now, and we're not terribly sick, just everything is working a little bit worse. Even like sinuses! Why does having less oxygen make your nose all stuffy?!
Edit: we're not at 12k, we're at 10,500 ft in upper Yubeng. And I don't think altitude does make your sinuses worse. I think we just both have a cold :P
