There's an announcement of a New Year's Day Drive at the Pelican Parts Forum:

New Years Day Los Angeles
-------------------------------
I have HEARD that some car enthusiasts will be meeting on New Years Day in the parking lots at both In/Out Burger and Denny's on Sand Canyon , right off the 14 fwy at 7:30 am.
I guess there will be a drive from there through the canyons and eventually end up in Montrose on Honolulu ave where there are a bunch of restaurants.

Hope to see you there to wish you a Happy New Year

TRE Motorsports has NO affiliation with this, and we are not organizing a drive ourselves.

Google Map to start.

I have no additional knowledge of this event.
