Except at rush hours-and this is partly the result of the city’s shape-you will probably have to wait what is for a metropolis a disgracefully long time-half an hour or more. Traffic is the excuse for delay. Actually, when your bus does come, it is ambling along with a tail of three or four others. They look like dinosaurs afraid to go singly. The first will be full of frantic people who have been gathering at every stop for the last half-hour. The trailers behind are nearly empty and their passengers are frantic because they have allowed twenty minutes for a ride which at this suddenly deliberate pace will take forty. The mind of man who can fashion a directed missile that will hit the enemy in the left eye but cannot make a schedule for New York buses.
