My mode of transport to the office this week is by Muni bus, the No 38 (the others : on foot, BART, Uber, taxi, street car). The bus is crowded, and carries the world : Indian people, Chinese, Korean, Japanese, European (tourists, but just one or two), African American and hey, even a South African American.
*Not really an option for me, unless I pack a folding bicycle like the one dude that got into the elevator today.
