so j.r. how would you like to drive bus in bangkok?
you might like this feature, too, j.r...thai public buses have fare collectors. passengers just jump on the bus, usually by the back door and the fare collector finds you to pay up. the fare ranges from 7-14 baht (22-44 cents) depending on if its window vented or has a/c and how far you are going.
prepared for a 10 hour bus ride from bangkok to chiang mai...sometimes you just gotta grin and bear it.
