Randy Plemel, who we last saw working on accessible transit maps, writes to let us know about the latest episode of his Smogr Alert podcast, in which he interviews Charles Graves, the author of The Genealogy of Cities (see previous entry). This is the first of two parts, but this is the part that deals with the book.

Previously: The Genealogy of Cities; Accessible Transit Maps.
