Silicon Valley

Looks like Detroit has been called out by California. Silicon Valley, located in San Francisco Bay Area in Northern California, has produced some healthy competition for some of the  auto companies who seem too comfortable in their current position as "kings of the automative world".  The west keeps expanding and Silicon Valley is growing right along with it, despite the development of other high-tech economic centers throughout the United States.  It remains the leading high-tech hub because of its large number of engineers and venture capitalists.
