But the Washington Metro is not as extensive as the NYC MTA. I've been on the DC Metro, and it's okay, but it isn't as comprehensive.
The L.A. subway is very nice, very clean, better trains than the DC metro, but it's so small, not comprehensive in the least, it's really too bad, a victim of corruption and politics. You can go from downtown to the Mid-Wilshire district, and from downtown to Hollywood, and two stops into the valley. That's it. You still need a car to live in L.A., basically.
The NYC subway on the other hand takes you, well, EVERYWHERE. The borough that is the least served is Queens (or Staten Island really, but Staten Island is so isolated as it is). But all in all, you dont need a car here, and that is one of the great things.
Like I said, New York is a great place to visit, and having the experinece of living in NYC is a great experience to have, I think anyone who has it is all the better for it, I'm glad I came, I dont regret it in the least, but make this my home? No way! For me, personally, I like the weather and lifestyle of L.A. The Mountains, the beaches of Santa Monica....look I used to live on the beach and woke up everday looking at the ocean and Malibu. It's SO depressing to wake up on a bright beautiful sunny day in NYC and be in the middle of so much concrete and general ugliness. I started going to Central Park all the time because I was starved for nature. But you know what? As beautiful as Central Park is...that gets real stale...Anyway..dont get me wrong...NYC is a great place to hang out for awhile, I just would never live here permanently.
