The setting for my story is New York City. How important is it to remain true to the geography of the city? I'm not sure if I should be specific in describing the locations of characters and using actual places (not major ones, like Central Park, but minor locations) or if I should keep it vague and let the reader's imagination create the visual around him. I'm wondering how important it is, if I say the character is on a certain street, if I describe the setting around him as close to reality as possible. Thoughts?
