Something strange is happening in the wheat fields of Lincoln County, Washington.
Huge crop circles recently appeared in a field owned by Greg and Cindy Geib.
The Geibs say circles are an almost yearly occurrence in the area, although this is the first time their farm has been affected.
They say they suspect pranksters are behind the mysterious designs, although the other possibilities are intriguing.
"I think it would be cool if it really were aliens," Cindy laughs.
