Sheridan Road north of Chicago starting in Evanston. You go by a number of Frank Lloyd Wright's including his only bridge. The wonderful Baha'i Temple with great gardens except in winter, the lake on the right and big houses from the 1920s to the 1950s on both sides. The number of them have been torn down in the last 20 years to put in some unfortunate choices. Also anywhere along this route you can usually head about a mile to the west and find the little money towns like Wilmette, Winnetka, Highland Park, and Glencoe. Many of them are loaded with their original shops and buildings from the early 20th century.
