I am glad you are enjoying yourself. I agree about the trams, they are a good means of transpor. In our town České Budějovice we have trolleybuses. There are¨two parallel electic lines above the streets and a special bus-like vehicle has two long thin trolleys that slide on the lines and collect the power from it. This means of public traffic has a long history, was cancelled in 60s and returned back in the end of the century. It works nicely!
