Plastique is right, Calabasas is 15 min. from Pepperdine and the beaches at Malibu, 1/2 hour from Hollywood

. It's in the mountains at the Woodland Hills end of a mini silicon valley that stretches up to Camarillo along the 101. Gorgeous, wealthy, semi-rural place to live right in LA - it's a unique area.
Amgen is a huge (their site is the size of a college campus) employer out here, and daily I pass places like Homestore, THQ (my kids test their games

), Digital Insight, Semtech, Spirent...
Oh yeah, every Wednesday night there's an IT get together at Spirent called
VANTUG (Valley NT User Group - jeez, sounds like a bunch of addicts!) with different guest speakers on relevant IT topics. Should be a great spot to pick up a few tips while you nosh & network. On that page you'll see a link to Diane at ThorIT; she's VERY knowlegeable re. the local IT employment scene and should be able to help you quite a bit.
Let us know how it goes - and good luck!
Meanwhile here's some
BOFH IT humor to cheer you up
