Crop circles appear at Washington wheat field

WILBUR, Wash., July 31 (UPI) -- A Washington state couple said crop circles that mysteriously appeared in their wheat field are likely tied to crop circles from previous years.

Greg and Cindy Geib of Lincoln County, north of Wilbur, said they noticed the crop circles in their wheat field Tuesday, KHQ-TV, Spokane, Wash., reported Tuesday.

The farmers said crop circles appear in the area every couple of years and this year must have been their turn. The couple said they do not know who is behind the crop circles, but they joked about them being made as signs from aliens.
