On his New York Times art blog, Christoph Niemann details his sons' obsession with the New York Subway system. These kids sound totally adorable and the drawings are pretty cute too.

According to Niemann:

Arthur spends hours studying the subway map. He laughs at his mother when she suggests taking the B on a weekend. The only questions he has are about the pronunciation of some station names...This morning he read the timetable for the No. 3 train and sang the stations to the tune of “Shalom Aleichem.” 

We are now reconsidering our stance on kids on the subway. They can be pretty great. Nothing in this world, however, will make us welcome children on an airplane.
