Er... The Bay Area's tech scene stretches all the way from San Francisco down to San Jose (and a bit beyond, even). That's a 50 mile drive all by itself. I recall when living in SF that the SF tech scene and SV tech scene were eerily separate because of the city/suburb divide. It's far from unified. Compare with the tech scene in NYC which is almost entirely based in Manhattan - a 5-mile stretch of it no less (from Bowling Green up to 59th St), that you can traverse by train or cab in a matter of 20-25 minutes. If pure concentration of people/companies is the X-factor, NYC should've trounced California by now :P
