Where in the World Is Farm Aid?

Willie Nelson's Farm Aid concert will have a new location this year -- a location that will keep us guessing for the next week.

Organizers of the annual event, which raises money to help struggling American farmers, have taken to Twitter to give fans one hint per day, for the next seven days, about where the 2009 Farm Aid will take place.

Hint No. 1 came today: "Your state feeling left out? This year's concert will be in a city and state where Farm Aid has never been held!"

So that rules out New York City, Champagne, Ill., Irving, Texas, Louisville, Ky., New Orleans, La., and more than a dozen other cities that have hosted the concert event. You can follow Farm Aid on Twitter to get the daily hints here.

Willie is joined by fellow music icons Neil Young, John Mellencamp and Dave Matthews on the Farm Aid board. Each year, huge names in country, rock, blues and pop come together to perform at the show, helping raise money and awareness for America's family farms. Farm Aid has raised $33 million for farmers since its inception in 1985.
