If you want to witness what architecture is about, visit SCI-Arc. This is where I went to school ,and I can tell you there is not one day that you will not be surprise what goes on inside this school. From open to the public lectures every wednesday to galleries and installation, and not to mention the student work.
This is the fast track from downtown to Hollywood. I get all my exercise here, it has the perfect amount of hills and is the by far the safest bike route, as motorists are more used to the cyclists than other streets. Anything you can think of is on Sunset Blvd, so I can pick up my dry cleaning, eat lunch, visit my friends, and exercise all in one trip.
