Everyone's favorite city, San Francisco has hosted three world's fairs: the 1894 California Mid-Winter Exposition, the 1915 Panama-Pacific Exposition, and the 1939-'40 Golden Gate Exposition.

San José, in the southern part of the San Francisco Bay Area, is home of Silicon Valley.

As a technology and creative capitol of the world with a diverse population, the region is ideal for a world celebration on the scale of a 2020 World's Fair.

Ideas for a 2020 World's Fair in San Francisco are shown at 2020WorldsFair.com with a Twitter feed at 2020WorldsFair.

Jim Wunderman, President and CEO of the Bay Area Council, has called for Expo 2020 to be held in the Silicon Valley.
