The Little Tomato is a nick name for the People's Republic of Davis in the fashion of New York city being the Big Apple, New Orleans being the Big Easy, or Chicago being the Windy City. The phrase was coined by Rob Roy during his 2008 bid for City Council. During the election Rob wrote a song called "The Little Tomato" which he performed in the crowd at Celebrate Davis as well as on stage at the Whole Earth Festival. The song can be streamed and/or downloaded here.
In 2010, much like he did for the 2006 Davis Wiki Fundraiser, Rob created a mix CD for the Local Wiki fundraiser entitled Audioversity in the Little Tomato: 6 Decades of Music Associated with Davis, Ca.
Fittingly, Sacramento has been referred to as the Big Tomato.
