I discovered Streewise Manhattan in a New York City bookstore years ago. I acquired a copy, and it quickly became my favorite map of all. Its format and sturdiness made it easy to carry with me without the map breaking down, and it was so easy to read, and to locate everything I wanted. I used it for years, and then - sadly - lost it.
I returned to New York and checked various bookstores there, and no one carried copies of it anymore, so I was thrilled to discover it on Amazon, and promptly ordered a new copy. After getting used to the Streetwise maps all others seem like pale imitations.
