accessible through a handful of canyon roadways and one major freeway artery that snakes in from downtown

I've been gone for 6 years now, but having grown up in The Valley I can attest that access to the rest of LA is by way of THREE major Freeways. The one snaking in from downtown is I-5, but they've missed the 170/101 (Hollywood Freeway) and the 405 (San Diego Freeway).

You'd think someone doing an article on a major city might have a glance at a map for about two seconds.

There were a couple of other points in the article that tripped me up, too. Like the one about two small mountain ranges. Yeah, I'd call the Hollywood Hills a small mountain range (the trailing end of the Santa Monicas), but the San Gabriels to the north are pretty good sized. The other was the line about newer suburbs to the north and east. What are they talking about? Porter Ranch? That's just a subdivision. Palmdale? Riverside? Not exactly new. I'd say if anything that the newer burbs are to the west (Calabasas, Agoura Hills, etc.) and the south (like far Orange County).
