A great abundance of things to see and do in addition to the commercial money-grabbers. Mount Wilson Observatory and the Palomar Observatory are worthwhile. There are also great architectural examples: Green and Green, Frank Lloyd Wright, Parkinson Brothers and much Art Deco. Regrettably, Shuttle Endeavor won't be ready for display until probably 2013. We have several outstanding museums, also. Griffith Park and the Observatory are fascinating, too.
I'll not mention the obvious studio tours and other film and television attractions.
Enjoy us!
