A southern Minnesota man created the Valentine's Day gift for his wife of 37 years in their farm field about 12 miles southwest of Albert Lea.
Bruce Andersland told the Alberta Lea Tribune that he started the project with his tractor and manure spreader Wednesday and finished Thursday.
His wife, Beth, says it's the biggest and most original Valentine she has ever received. She says some people might think it's gross, but she says it's cute and "Why not do something fun with what you got?"
She says the heart would be darker except for the recent heavy snowfall that mixed with the manure.
