My other favorite route is in Manhattan along the Hudson river south toward lower Manhattan. The views aren't as spectacular as from Brooklyn but looking over at Hoboken and Jersey city as well as watching construction of the Freedom Tower makes the miles go by fairly quickly.
Throughout the year the routes naturally change. Flowers come and go, leave change colors, and there is an occasional (very occasional this year) bit of snow.
Do I think I'm lucky to be a runner in New York City? Heck Yes!
