Tourons on Red Line from Silver Spring -

Kid 1: This is gonna go underground!
Kid 2: This is gonna go underground? Mom, its going to go down?
Mom: Yes, the train will go underground
Kid 2: But you mean, like down a hill?
Mom: (pauses) Not like a roller-coaster.
Kid 2: (turns back around and crosses arms) Well that's no fun.
