Invasion of the iPod listeners

Philadelphia is the city of Brotherly Love, and it is also home to many an
iPod listener, and during my various treks through the city I have seen more than my fair share of the tell tale white headphones.

Khoi Winh, a resident of New York City, has noticed the same phenomenon in his fair city and unlike me he did something about it. He
printed out a map of his walk from his home to work and marked the map with a red dot each time he saw an iPod listener. A little over 13 blocks later he saw 32 iPods. Not too shabby.

What other cities are being overrun by iPodders?
