Seems it is hard to come by U-Hauls in Silicon Valley these days. There has been a major exodus from the area, both due to a decrease in jobs and the increased employment of telecommunting.
WebGuild reports that thousands of people are leaving the area and few are coming to replace them.
Interestingly H-1B visa applications - people applying to enter the US for work purposes - are also down. Usually the applications are closed almost as soon as they open availability April 1 - but as of today the 65,000 available slots had not been filled or applied for fully.
I personally know two people planning on moving from the area to Florida. Guess the weather, no income taxes and lower real estate prices are a big allure.
