What interests me about the letter of Walt Whitman posted here (text below) is his feelings about his native city, New York. They are similar to mine.
Whitman, then working as government clerk and a volunteer in hospitals in Washington, DC, was visiting New York at the time the letter was written. He was staying at his mother’ s house on Portland Avenue in Brooklyn.

Dear comrades, as I did not finish my letter yesterday afternoon, as I had many friends come to see me, I will finish it now—the news this morning is that Meade is shoving Lee back upon Richmond, & that we have already given the rebs some hard knocks, there on the old Rappahannock fighting ground. O I do hope the Anny of the Potomac will at last gain a first-class victory, for they have had to retreat often enough, &: yet I believe a better Army never trod the earth than they are & have been for over a year.
Well, dear comrades, it looks so different here in all this mighty city, every thing going with a big rush & so gay, as if there was neither war nor hospitals in the land. New York &: Brooklyn appear nothing but prosperity & plenty. Every where carts & trucks & carriages & vehicles on the go, loaded with goods, express-wagons, omnibuses, cars, &c—thousands of ships along the wharves, & the piers piled high, where they are loading or unloading the cargoes—all the stores crammed with every thing you can think of, & the markets with all sorts of provisions—tens & hundreds of thousands of people every where, (the population is 1,500,000) , almost every body well-drest, & appearing to have enough—then the splendid river & Harbor here, full of ships, steamers, sloops, &c—then the great street, Broadway, for four miles, one continual jam of people, & the great magnificent stores all along on each side, & the show windows filled with beautiful & costly goods—I never saw the crowd thicker, nor such goings on & such prosperity [italics added]—& as I passed through Baltimore.& Philadelphia it seemed to be just the same.
I am quite fond of crossing on the Fulton ferry, or South ferry, between Brooklyn & New York, on the big handsome boats. They run continually day & night. I know most of the pilots, & I go up on deck & stay as long as I choose. The scene is very curious, & full of variety. The shipping along the wharves looks like a forest of bare trees. Then there are all classes of sailing vessels & steamers, some of the grandest & most beautiful steamships in the world, going or coming from Europe, or on the California route, all these on the move. As I sit up there in the pilot house, I can see every thing, & the distant scenery, & away down toward the sea, & Fort Lafayette &c. The ferry boat has to pick its way through the crowd. Often they hit each other, then there is a time—
My loving comrades I am scribbling this in my room in my Mother’s house. …
