In Toronto, I grew up taking a subway, I grew up taking a bus. I spent my formative adult years in New York City, walking the streets, taking the subway. You're connected to the larger whole. L.A. is so spread out, and you're so incubated inside those cars and it's so exhausting to deal with the traffic, without really having the human contact.
If actors could actually make a living doing theater, that would be my first choice. Sitcoms are the closest thing to being onstage in front of an audience. If I had to choose, it would be theater and doing the occasional movie once in a while, and spending time doing nothing.
