illusion?

I looked out the window just now, and I can see the big dipper. It must be an illusion, because
It looks enormous. I know that I am a few thousand feet above sea level now, but I cannot comprehend that it makes that much of a difference!! It is huge compared to what it looked like when I would be sitting out by our pool... interesting.. and with that, I am off to dream land. More to come tomorrow!
