Changes

On the buses there is control after 21.00, because that is (when the controllers get stop their work day) one has to enter at the day off. Before front and show the driver their ticket, before then, one should be really careful, because the conductors will can come with a whole bunch of people and won't let anyone out. Better to take the tram - according to a friend who grew up in Zurich the chance is very small that there will be a control, and after 21 there won't be any controllers at all.
