Here are resources to inspire and guide an exploration of Laura Ingalls Wilder sites:
A good place to begin, with information on festivals and much more, is www.laurasprairiehouse.com.
Beyond the standard "The Little House" books (available individually or as a set), there is "The Little House Cookbook: Frontier Foods From Laura Ingalls Wilder's Classic Stories," by Barbara M. Walker and Garth Williams ($9.99) and "The Little House Guidebook," by William Anderson ($9.99).
You can also get "The Little House" audiobooks, by Laura Ingalls Wilder, performed by Broadway actress Cherry Jones on cassette and CD. ($14.95-$25.95). Listen to them in the car as you drive from site to site. Jones is a lovely reader, with a wonderful singing voice. More inspiration can be had with the CD "Happy Land: Musical Tributes to Laura Ingalls Wilder" ($15.98) and "The Little House on the Prairie," a fantastic feature film, not the television series ( $21.99).
