Google Street View Photos

On November 4, 2008, three more U.S. cities were added: Washington, D.C., Baltimore, and Seattle. More parts of Seattle are available in high quality view (like Mercer Island and center of the city).
On December 9, 2008, extensive coverage of the United States was added. This included full coverage of all large and most medium-sized urban areas and most major highways and connecting arteries throughout the 48 contiguous states.
On March 18, 2009, extensive coverage of the United States was added including most of the coverage of Delaware, North Dakota, Rhode Island, and South Dakota. For a period of time some coverage was deleted (such as in northern Minnesota.)
In Canada, Google Street View cars had been spotted as early as September 2007, in Montreal.
