I was shocked at the number of bicycles in Amsterdam. Which is wonderful, I think we should all cut down on the time that we spend in our cars. However, walking on city streets is dangerous. Traffic flow in Amsterdam seems to be chaotic without rhyme or reason and everyone yields to the bikes. Any given street will have two bike lanes, lanes for cars, then in the middle, a bus/tram lane. Before you cross any street it is necessary to look back and forth about five times, then cross your fingers and pray as you run.
