I live in Seattle now and I dearly miss LA. I still love the Seattle area for the mountains, but as a city, LA is my favorite in the world (yes I've visited plenty of others and my sister lives in NYC).
You said you missed mountains around Seattle, so I had to point out that while not glaciated, the Gabriels and San Bernardino mountains are breathtaking in their own right. And the Sequoias by Yosemite just 4 hours north arent bad either where you have peaks over 14K feet. I live in the mountains, I moved to California for the mountains.
