Werner Herzog describes LA as “the city with the most substance anywhere on earth”. The thing with LA is that it can be anything. It’s so huge, and so diverse that you can find absolutely anything your heart desires there if you seek it out. There is the superficial glamour of Hollywood, but also the high tech cutting edge manufacturing of aerospace, endless immigrant communities from every corner of the world, every food imaginable, even family friendly enclaves of community. LA requires that you know what you are doing and what you want; it wont drop anything in your lap. But the heights of experience to be had there are like nowhere else.
Don’t forget that to experience all this wonderful stuff you have to contend with one of the worlds worst traffic problems.
I called LA home for two decades and the transportation hell largely kept me in my general community. Going to Pasadena from the Westside is a full day commitment, unless you leave at sunrise on a Sunday.
