The WB (and, later, The CW) drama One Tree Hill lasted for the better part of a decade. Set in the fictional town of Tree Hill, North Carolina, the series followed the lives of five main characters, who began as high school students, but later grew up and married their sweethearts. One of those characters was Peyton Sawyer, played by Hilarie Burton.
