All Night Subway/Light Rail Service New Year's Eve

Earlier this month, Metro announced the usual free rides on Christmas and New Year's Eve special that they do every year. Tonight, we received a short and brief, but extremely exciting e-mail:
"On New Year's Eve Monday, December 31 (into Tuesday, January 1), all Metro Rail lines will run all night, every 20 minutes."
Yes, that's all it said. No further details were mentioned (we're sure they are forthcoming, we are curious what "all night" really means), but it's enough of a holiday present to Los Angeles to make many rejoice. So rejoice and take advantage!
