Rockridge, california
At the foot of the Oakland Hills, Rockridge is a lovely burby-like haven where Cal Berkeley grads come to live when they exit their 20s and start yearning for historic cottages, nice gardens, and a 86 walk score. Twitterites and techies who have newly flown the coop are lucky to nab a place to live in this desirable hub. Even so, all ages come to explore this model main street where two indie bookstores thrive.
