One of the best things about New York is its street grid: avenues go from North to South across Manhattan and streets from West to East. This makes it very easy to get around. It is also the kind of city layout that I came to miss when I returned to London, where streets seem to have little appreciation for consistently being geometrically perpendicular and prefer to function in concentric circles instead.
One of the best things about the New York grid is the fact that, cross any avenue or street you may, you always have the ability to see North to South or West to East as far as the eye can see. There is no building getting in the way of the vista, as they are all consistently aligned to the avenues or streets that delimitate them.
I have many times dangerously stopped in the middle of crossing 1st, 2nd, and 3rd, Lexington or Park and many other streets to take in the view. The window that allows you to see as far as Harlem and as down south as Downtown New York; from the West side to the East side.
It is almost as if the curtain of buildings and skyscrapers that makes up the fabric of New York pulls itself and allows you to take in the view. Probably my favourite New York feeling: seeing this curtain pulled and breathing it all in.
