It was a beautiful summer day in New York City. It was a day made for walking. John was standing at an intersection near the Brooklyn Bridge. He had driven over the bridge before. But he had never walked over the bridge. He started walking uphill on the pedestrian path. Many people were walking ahead of him. Many people were also walking toward him. They were coming from the Brooklyn side of the bridge. A bicycle path was next to the pedestrian path. Some pedestrians were walking on the bike path. A bicyclist approached. He rang his bicycle bell. Walkers slowly got out of his way. He kept ringing his bell. John continued walking uphill. A man was standing next to a large ice chest. He was selling bottled water. "One dollar! One dollar! Ice cold water!" he shouted. John wasn't thirsty. He wondered how heavy that ice chest was.
