For organizational purposes, "Downtown" by our standards is anywhere in Manhattan below 23rd street all the way down to Battery Park, regardless of how you may define your regions throughout the city. If you're looking at this as a tourist, then Downtown would probably be your safest bet when it comes to skating the most spots. 75% of the spots here are at most a fifteen minute skate from one another, with several being as close as across the street from each other.
