We periodically get together, usually on a Saturday (to avoid rush hour) & usually in the LAX area (Manhattan Beach, Westchester, Hermosa Beach) as it's 'in the middle' from both the valley & OC.
I don't know that anything is planned for December though, as folk are flying to get status by year-end plus go out of town for the holidays.
I'm sure we can organize something for January '06. Cheers.
