Dallas, Detroit, Indianapolis, Fort Worth, Boston, Minneapolis/St. Paul, and Providence have their cities added to the Google Maps Street View. It's only a matter of time before Knoxville, TN, gets added as I found out I wasn't the only one that saw the mapper here. (see:Google Maps Street View Hits Knoxville, Pictures of Chevy Cobalt)
All I can say is that they could've left Detroit to the last of the updates. That's one of the ugliest cities in North America.
