PID Ferry Sign, Dvorce, Prague, CZ, 2009

I took the tram to Dvorce not to get another tram or bus, but actually to take one of the new PID (Prazska Intergrovana Doprava) ferries. These ferries have the same old DPP maps and schedule sheets as the trams, Metro trains, funiculars, and buses, even though they don't run officially under DPP. The DPP passes are, however, valid on them, same as on Ceske Drahy, as CD, DPP, and the ferries are what make up PID.
