Greg's neighborhood consists of his school, the home of his grandmother, and the homes of Rowley, Holly Hills, Leland, the Snella family and Fregley. His adventures in this neighborhood were first drawn by Jeff Kinney in 1998 and published as a daily web series in 2004. The print book "Diary of a Wimpy Kid" was published in April, 2007. The second of the series, "Rodrick Rules," was published in January, 2008.
