I wish Palo Alto could get out of their limited and never very awesome metro fiber business (run by the city, like their other utilities) by getting Google as a partner. For Google, it would make sense from a marketing perspective -- if I got 1Gbps fiber at home in PA due to Google, I'd be more positively inclined toward the company in general (for working, M&A, other products, whatever).
San Francisco, I have zero hope for due to the totally dysfunctional city government, but Palo Alto, Mountain View, maybe EPA (for political reasons), Menlo Park, Sunnyvale, Santa Clara, Cupertino all seem pretty sanely governed.
If EPA had Google Fiber, I'd probably brave the (moderate, now) security risks, air quality, and floodplain.
