According to my sources, in the Pacific Northwest, Mount Rainier put on an interesting cloud show a couple Friday's back.
When I was in Tacoma in August of 2008 in the early evening I was on my way to Top's Grocery when I saw similar clouds over Mount Rainier. Plus it was a full moon. I have never in my life been more aggravated that I did not have my camera with me.
Go here for more Mount Rainer Flying Saucer clouds and the story of how way back in 1947 a pilot named Kenneth A. Arnold sparked the era of people seeing Flying Saucers when he spotted 9 UFOs near Mount Rainier.
