According to my local newspaper's website, Santa Claus is giving out free train rides on the light rail and subway to folks.
Metro trains and buses will be free on Christmas Eve, but not on our local bus system, nor on Metrolink trains.
This also applies on New Years Eve, until 3 am. With ten-minute LRT frequencies on the "Gold" line to and from LAUS to the parade route in Pasadena all night long, and all-day on New Years Day.
