Changes

Black-riding is possible and most of people in Zagreb who don't have monthly or yearly tickets do this in trams and in buses there is almost no control. Controllers are sometimes all over the town but mostly there is nobody for months. There are in groups of 2-3 wearing blue uniform just like the driver so if you see them just get out and wait another tram. Playing the "dumb tourist" will work because they don't have authority to ask you passport or your id and if you give them your passport they can't send you a bill to your home because you are not citizen of Croatia. Also they will not call police because there are city owned company and controllers have fixed paychecks so they don't give a damn too much.
