I crossed that border into the Upper East Side. Had a bread pudding muffin & expensive mediocre coffee & saw a friend & fancy holiday wreaths & tiny scooters lined up in front of a school & some churches (Saint Thomas More) I've never noticed. It's where Johnny grew up, he knows this neighborhood. But surely this is not the working-class Yorkville of his childhood? It's not my city any more than Sioux Falls would be his even if we moved there for the next 50 years. The border is between theh present & the past. That's a lot farther away than East 83rd Street.
