The Case of the Calendar Kids

Jennifer and Gary came to visit few couple weeks ago, and as we chatted I mentioned that Walker Physics had appeared in the online version of the New York Times.  The article was about students trying to pay back their student loans, and the photo showed a student in his dorm room with a copy of Walker Physics sitting on the desk.
