Re: Cali: LA and San Fran guppies :)
Faisal has repplied well and I can add a little more into it.
If you like nature then should definitely driver along highway 1 from San Francisco to Monterey. You will find some breathtaking views and scenes along the coast.
If you are fascinated with high tech then should drive through Mountain View, Sunnyvale, Santa Clara in order to see Google, eBay, Yahoo, AMD, Intel HQ's. Oracle has beautiful campus too. You should also visit Stanford University in Palo Alto - a really beautiful and fascinating campus.
