The deteriorating log cabin at the “Little House on the Prairie” site in Kansas is expected to soon get a makeover. The current cabin was re-created and built near Independence in 1977, during the peak of popularity for a television series based on Laura Ingalls Wilder’s books centered on her childhood. Wilder spent a year with her family at the Kansas site in 1869. Siblings Bill Kurtis and Jean Schodorf, who own the cabin, said four decades of weather in Kansas has worn down the house. They want to rebuild it and add a barn. More than 20,000 people visit the site each year. But with the current cabin drooping and logs weakening, its interior is barred from the public for safety reasons. About $30,000 has been raised to rebuild the cabin, but the owners need nearly $20,000 more to help pay skilled craftsmen.
