Diana, sorry you can't make it. Best wishes for your mom's surgery.
Cheers.
PS - In case any of the out-of-towners are reading this, bring quarters for the meters. There's parking on the street, but also some parking structures. An underground one on Manhattan Beach Blvd (2 blocks up from Beaches); entry either via Morningside or Valley. There's also a 2-story structure, entry from Morningside (off Manhattan Beach Blvd) or 12th street. It's metered parking through 8pm.
