I saw 2 at work. I went upstairs to the roof at work, which is a test site, about 5:15 AM. Little quick ones. High atmosphere here in L.A. A few years ago, when it was very cold and hazy, I say a very bright one light everything up. That was a big one.
It was like an Angel fly-by to tell me to finish the coffee, put out the ciggie, and do what I am there to do.
