Sarah Palin avoided questions about her presidential aspirations Saturday during a book event in Des Moines, Iowa.

The former Alaska governor's latest visit to the state — her third since 2008 — has prompted speculation that she is working to establish herself there before 2012.

According to The New York Times, however, Saturday's three-hour book event saw no hints from Palin about her plans.

Asked whether she would run for president, she said "Oh my goodness!" and thanked an autograph-seeker for helping her "change the subject."

She held no media interviews, according to the AP

The book tour itself has been called untraditional because it will forgo major coastal cities.

Palin has tweeted favorably about her experiences in the "Heartland" so far:

Thank you Oklahoma!We appreciate you! Just landed in crisp & cool Nebraska;look forward to tomorrow's America by Heart book event in Norfolk

Her book, "America by Heart," was released Tuesday. She will be back in Iowa for another event next Thursday.
