My favorite block in New York City is Columbus between 67th and 68th. There's something about the shade on the sidewalk as the light hits the trees, and the red brick apartment building and the orange awning over the wine shop, and the fact that it's a wine shop. I tried to shop for wine there once but the aisles were exceptionally narrow and I was afraid of causing destruction with my overeager stride. But the block is perfect.
Another time I waited for a bus across the street and overheard one woman telling another woman that she had to move out of that red brick building soon because the rent had gone up, and we all sighed together simultaneously even though I wasn't even part of the conversation.
There's a post office on the opposite corner, and the AMC Loews Lincoln Square cinema is a short block away. I've seen an insane number of movies there, dating back to The Holiday on January 1, 2007, and I have the many Swarms to prove it. The best Barnes & Noble in the world used to be just down the street, too, where the literate and lazy would sprawl out on the floor and read theater books and where I once saw the cast from the revival of Company perform a few hits from Company, but that store closed in early 2011 because nothing gold can stay.
