Changes

On the night busses buses there's almost always a is controlafter 21.00, on because that is when the controllers get the daytime busses you day off. Before then, one should be really careful, because the conductors will 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.
