I don't really like L.A. all that much. I've never been able to successfully make it through the area (even as far away as San Bernardino) without being in some inexplicable traffic jam somewhere. As a city, it seems like it was pre-assembled with one purpose and then people were allowed to move in with some other purpose in mind. I don't know. Except for the beach areas, which have their own order of things, the city just doesn't make a lot of sense to me at all.
There are some really beautiful places there, but everything is two hours away from everything else, and between you and your destination are at least three people who are driving slowly in rented luxury cars hoping to see or be seen by someone famous. Although it isn't totally constructed of image like Las Vegas is, somehow it seems even more fake.
Of course I'm speaking as a San Diegan, so I have a lot of L.A. issues in general. It is between me and Las Vegas, and always slows me down at least an hour. If I'm not flying Southwest I'll probably have to land at LAX before I am allowed access to the rest of the country. It monopolizes the term "Southern California," and to a lesser extent California style itself. L.A. speaks for more people than it represents, and I kind of resent that.
Some darn good restaurants, though.
