The Huntington in upper-crust San Marino offers a hybrid of the Library of Congress, the U.S. Arboretum, the U.S. Botanic Garden, and Hillwood Estate -- and you only have to park once.
Drive or take the Expo Line to Exposition Park for LA's Natural History Museum (where you can party after hours with bugs, dinosaurs, DJs, and booze the first Friday of each month). Also here is Air & Space Museum-ish California Science Center, home to the Space Shuttle Endeavour and a bunch of chicks. (They’re baby chickens, but still.)
When you start to feel nostalgic for the street art of Blind Whino, Union Market, Blagden Alley, and Adams Morgan, buck up and head to DTLA’s Arts District to feast your eyes on wall-bound works by artists like ROA, How and Nosm, and Tristan Eaton.
