I just purchased this map for friends who are visiting from Canada. I first found out about Streetwise Manhattan when I was an NYPD Field Training Officer back in the the 1980's. The Association for a Better New York, then under the direction of former NYC Mayor John Lindsey, gave us cases of maps to issue to new police officers assigned NSU-3 in Mid-town Manhattan. With Streetwise Maps our Officers were able to give specific directions to visitors and residents on where a place was and how to get there. It does not give a description of a place just the location and how to get there in an easy to read format. The map was folded and ringed to exactly fit in the NYPD issued memo book holders. The NYPD copies did include some specific information not listed on the regular copies back then. I myself used the map to give countless directions to people and other Officers when I was assigned to the area around the United Nations. I also frequently gave away my copies to visitors when they asked me. When my son and sister were appointed to the NYPD and assigned to Manhattan I gave them copies. My father use to give copies to co-workers visiting his New York office, so they could explore on their own. One of his business associates was staying at a hotel on Central Park South at 5th Ave. and looking for Central Park and FAO Schwartz on the corner of E59th St and 5th Ave. The map let him know that he was there. Central Park South is also called W 59th St. Avenue of the America's is also called 6th Ave and Lexington Ave 4th Ave by locals. I do find it odd that with all the copies I gave away I now have to purchase a copy. If your coming to experience New York, and everyone needs to visit and enjoy the energy, arts, shopping, museums, and everything else that is New York at least once, you need a copy of this map and an MTA card for the buses and subways to get around. And yes the subways in Manhattan are safe, fairly clean, and the best way to get around.
