In-valley transport actually sucks. I commute from Alameda to Mountain View - it takes 2.5 hours via public transport. :( (37 miles).

Bike --> Bart --> Cal-Train --> Bike (and reverse, $20 total)

This is one thing that interestingly has been both ignored and solved by tech companies. FB, Goog, Gene - they all have very effective troop transport. But by-in-large, silicon valley has done nothing to provide a solution to the problems with transportation and data access.

(WRT data access: DSL wasn't available in the heart of SV for several years after it was widely avaialble. Cellular coverage from AT&T has had the SAME EXACT dead spots on 280 and 101 corridors for TEN FREAKING YEARS! -- No widely available wifi, data coverage on CalTrain and Bart is horrendous!)
