slow moving fireball the day before a local crop circle story was in the newspaper

I was sitting on my back porch facing east, looking at the stars and having a cigarette pretty early in the morning hours.  I had seen a few meteors streak the sky every once in a while and watched a satellite move by.  Then, I saw a big slow fireball coming toward my direction (from east to west) then going where the porch roof blocked the view overhead. I thought how weird a meteor could be that slow and big. I got out of my chair and looked weset over the roof and saw the fireball finally disappear in the night sky which I thought nothing more of.  THEN a day or two later the union bulletin (our local paper) had a story with pics of a crop circle in walla walla.
We suspect the witness may be alluding to the crop circle that appeared in a wheat field on a north facing hillside, just south of Kennewick, WA, which is believed to have first appeared on, or about, Saturday morning of the Memorial Day weekend in 1993.  I will attempt to confirm the date.  PD
