The subways ..
Frankfurt (am Main – on the River Main) reminds me of Toronto or Philadelphia – practical and inexpensive. Now they’re armed with subway, navigating the city becoming event more convenient. Talking about subway, Underground, S-Bahn, Tram, etc to the Germans while Metro for Parisians, it’s amusing to see that there are plenty tall fare gates guard the Paris Metro (and plenty people trying to beat it, some due to malfunction .. ) while German’s subway were wide open, without a hint of gates, purely on honor system. Two countries share long border but drastically different.
