After stopping at three more stops since San Mateo for other tour people, we've departed for Needles, AZ, for our first night's stay. Tour guide KHsu currently telling us not to use bus toilet ('steaming cake') unless necessary to keep bus from stinking 'like cake' (with accompanying obligatory horror stories). I'm surprised I could understand Mandarin as well as I did without close captioning. The gramps behind me repeats everything KHsu says.
