Walking is the safe option...
I do have a bee in my bonnet. Just one. That´s the Fortaleza bus system.
Although there always seem to be plenty of people on them, no-one - and I mean no-one - seems to know which one I need to take to get from one side of town to the other.
And the attendants on the bus are no better. Yesterday I asked one if we went to the beach. Yes, he said, only for the bus to turn around at the next junction and go back on itself, AWAY from the beach.
