At the beginning of each tour (allow one per day), find a bench in one of the many small parks and read the introduction to the tour. While you take in the sights, smells and sounds of the area, you'll learn a bit of history to set the stage for the tour. The walks are slow and intend for you to really look at your surroundings as you read about the history, architecture and people. I wish there were guides like this for every city!
