The Superbowl is my favorite day of the year. It's the one day where there is no traffic, no lines, and plenty of room on trails and waves, but it's not a holiday, so everything is still open. They should have it twice a year really.
My second favorite day, especially in Los Angeles, is the Oscars. The Oscars are SOOOO important here that they have to be shown live, which means they come on in the afternoon so the east coasters can see them in primetime. Count in the pre-shows and all that, and it's pretty much another day when everyone is inside watching TV. It isn't quite as empty as Superbowl Sunday, but it's close.
Granted, you have to avoid Hollywood entirely, as amazingly they have had Hollywood Blvd closed for a week leading up to the Oscars, but it's pretty easy to avoid Hollywood.
