With live art performances all day and a nice big open park area, it's a time to chill and enjoy what the surrounding museums bring to LA. Last time I went, they had some free goodies handed out. Maybe some free drinks. Remember to get a ticket from LACMA still, you have to go to admissions first.
Not only museusms, but galleries around the area will be open to show off some there best work.
You can start at
5905 Wilshire Blvd
Los Angeles, CA 90036
but go up and down the Mircale Mile for all the sites to see.
