MANSON, Wash. - Charles and Linda Everson were driving back to their hotel when their minivan was struck by a falling object - a 270-kilogram cow.

The Eversons were unhurt but the cow, which had fallen off a cliff, had to be euthanized.

The year-old cow fell about 60 metres from the cliff and landed on the hood of the couple's minivan, causing heavy damage.

A Chelan County fire chief, Arnold Baker, said the couple missed being killed by a matter of centimetres in the accident Sunday on a highway near Manson.

The Eversons, visiting the area from their home in Westland, Mich., to celebrate their first wedding anniversary, were checked at Lake Chelan Community Hospital as a precaution.

Everson, 49, said he didn't see the cow falling and didn't know what happened until afterward.

He said he kept repeating: "I don't believe this. I don't believe this."
