From Graceland to the world's largest ball of twine, quirky pop culture attractions have offered many tired travelers a diversion along the road.

But some of these uniquely American offerings may be dwindling as people's tastes change.

Indiana officials are expected to close the historic state site honoring the celebrated World War II correspondent Ernie Pyle.

The owners of the Iowa house and baseball field where the 1989 movie "Field of Dreams" was shot have put that attraction up for sale.

Here's a look at some Midwest attractions that remain:

*Laura Ingalls Wilder Historic Home and Museum, Mansfield, Mo.; house opened in 1957, the museum in 1971.

Main attraction: Home built by Wilder and her husband with original furnishings. Museum holds other personal items like quilts, dishes and her father's fiddle.

Annual visitors: About 35,500

The draw: "People relate to her pioneer spirit," said director Kathleen Forte. "And, of course, the stories that she wrote bring it all to life."

*James Dean Gallery, Fairmount, Ind.; opened in 1988.

Main attraction: Museum displaying original movie posters, yearbook photos and an exhibit of the car accident that killed Dean, who died at the age of 24.

Annual visitors: About 12,000

The Draw: "A lot of it is in the way he looks, just so cool and modern," said owner David Loehr. "Young people especially identify with him as a symbol of teenage angst."

*John Wayne Complex, Winterset, Iowa; opened in 1982.

Main attraction: The city of Wayne's birth. A museum located in his former home boasts movie costumes, old photographs, guns and movie posters.

Annual visitors: About 30,000

The draw: "John Wayne defies the law of optics," said executive director Brian Downes. "The further away we get from him, [the more time passes], the larger he becomes."

*Buffalo Bill Museum,

LeClaire, Iowa; opened in 1957.

Main attraction: The city of Bill's birth. Artifacts and memorabilia about Bill, including items from his Wild West show.

Annual visitors: About 7,000

The draw: "He represents the Old West," said director Bob Schiffke. "In his time he was probably the most famous person in the world ... someone like Michael Jackson ... and it just carried on."
