The Nutty Nomads are a pair of urban explorers who happen to be sisters that love to document their adventures in L.A.

Last week they tweeted @MetroLosAngeles to let us know about their latest video: Metro Challenge.

The challenge? Visiting some of L.A.’s best sites without a car! The Nomads ride the bus, subway and light rail to visit Olvera Street, Little Tokyo and Chinatown.

The video offers a good primer on riding the Metro system as well as some interesting facts about Union Station and Olvera Street. Check it out!
