On our way back from the Yangze we saw a sleeper bus and those of you who know me know how hard it was for me not to take pictures. I guess the people get on the bus and it goes forever. Several of our students talk about 40 and 50 hour train and bus rides and I guess that is the function of these buses. They have seats that are in a permanent reclining position so you basically lie down and you can sleep. The people seem to be pretty content and they pile out of the bus when it stops for potty breaks.
