Remember Sarah Palin's One Nation Tour that kicked off May 29 and ended in a fuzzy retelling of the Paul Revere story? Well, One Nation is back at the road and on its way to visit the Iowa State Fair Friday on the eve of the leadoff caucus state's GOP presidential straw poll.

"The heartland is perfect territory for more of the One Nation Tour as we put forth efforts to revitalize the fundamental restoration of America by highlighting our nation's heart, history and founding principles," an announcement posted on Palin's Sarah PAC Web site stated Thursday. The site also features a new video (below) hyping the trip.

In case you forgot the details of the former tour, here's a recap of some of the highlights:

-Face time at Rolling Thunder - an annual Memorial Day weekend motorcycle rally in Washington. D.C.

-A chat with locals at Coffee Express in Dillsburg, Pa.

-Pizza with Donald Trump in New York

-Breakfast at the Golden Egg in Portsmouth, N.H.

Of course, her most memorable stop was at the Old North Church in Boston where she said this about Paul Revere:

"He warned the British that they weren't going to be taking away our arms by ah ringing those bells and um makin' sure as he's riding his horse through town to send those warning shots and bells that ah we were going to be secure; we were going to be free."

After the media pointed out some flaws in her American history, she simply claimed:

"You know what? I didn't mess up about Paul Revere. Here's what Paul Revere did: he warned the Americans that the British are coming . . . and they were going to try and take our arms so we gotta make sure that we were protecting ourselves . . . and a part of his ride was to warn the British that we were already there. That, 'hey you're not going to succeed, you're not going to take American arms, you are not going to beat our own well-armed persons individual private militia that we have.'"

To quell any questions of Palin's knowledge of American history, she did have a painting of the Constitution on her bus along with an American map (though it showed Alaska roughly the size of half of the continental U.S.).

Palin kept reporters literally chasing her oversized vehicle up I-95 in order to cover her every move after she refused to give out details of her travel schedule.

Details of her latest bus tour remain unknown.

Palin has not been shy about staying in the media spotlight, often outshining Republican hopefuls for the 2012 ticket.

Though Palin has kept her intentions a mystery, she launched the One Nation tour on Memorial Day weekend, following a path of historic American sites up the East Coast to New Hampshire on the day that Mitt Romney announced his candidacy in the state.

Then in June, she headed to Iowa to attend the premiere of her documentary "The Undefeated" as Michele Bachmann made her candidacy official there.

Palin will likely be the center of attention again this week in Iowa as Texas Gov. Rick Perry is set to signal his intentions regarding the 2012 election.

According to Real Clear Politics:

"In spite of the celebrity profile that she has embraced since 2008, the unorthodox nature of the bus tour indicates that Palin recognizes that she would have to run a grass-roots campaign that removes some of her shine, in order to highlight her blue-collar persona."

The One Nation tour also threatens to outshine President Barack Obama's three-day bus tour of the heartland in Iowa, which begins on Monday.

Have a look at Palin's tour promo below. Palin's voice narrates a series of bucolic images, including small town parades and farms, though the audio is from her speech at the 2008 Republican convention:
