because it's been snowing for the past twenty-seven hours. And i stayed up to see just incase there was a temporary clearing.
I have seen it in Madison, WI and northern WI several times. Once in the summer of 1983 it was so intense in Madison that I saw it under massive lights in a hospital entryway. When I got home a few blocks away but not so well lit, I could even hear it as waves of rainbow colors moved about overhead. I was amazed. But Madison isn't a very smoggy city. I can imagine there isn't much you can see through the smog. I remember LA in the 70s through the 90s and you could barely see Venus through that stuff and the moon didn't cast a shadow. Yuk.
Up here at 7K ft., you can see so much it give you chills up your spine to realize how much is out there. And just looking through some binos will really give you something to keep you awake at night! The only smog here is from wild fires anywhere west of here and exhaust from those damned two-stroke snowmobiles that hangs in the air for a long time when it's cold out.
