Yes, Los Angeles does have a mass transit system, including subways!
When travelling to downtown or Hollywood it’s actually quite easy to get to one of the stations on the subway, particularly on the weekend or in the evening. We don’t have a subway line terribly close to us (although there’s a dedicated bus line only a couple miles away that goes to the station at the end of the subway line) but it boils down to parking for $3 at the subway station that we’re driving past and $2.75 to get to Hollywood, or driving to Hollywood and paying $25 (or more) to park and having to deal with a ton of nasty traffic.
The LA Metro system, when you’re in that envelope where it’s going where you’re going, can be quite useful.
And a lot of it is gorgeous as well. The stations are all relatively new (the entire system only started twenty-five years ago) and there’s a lot of interesting designs and artwork involved.
When we went to the Pantages to see “Waitress” yesterday, we started out at the Universal City station.
