Art's a trip...

Every first Statuday and Sunday of the month MTA (Los Angeles major Train and Bus system) gives free tours of the art at Union Station and different stops on the Red Line Subway. You can meet @ Union Station in Downtown for one tour or Hollywood and Highland  in Hollywood for another. This is a 2 hour tour with no bathrooms a long the way. It is FREE and the best part of all is they give you a day pass just for coming that you can use for the remainder of that day (12 midnight).
