Chris Lovett interviews Andy Woodruff about his new book, Boston in 50 maps - including a "heat map" based on people's feelings about that eternal Boston topic: Where one neighborhood ends and another begins - as well as his inspiration: An earlier poster, Unmapped Boston, by Max Harless, that shows zillions of Boston (and nearby) squares and circles and key points.

Note: The link to the book takes you to Amazon, where UHub would get a small fee if you then buy the book.
