On day one of the drive, I saw my first dome sky. The world was so flat that I could see the level horizon all around me and the sky looked like a dome. Skies like that will give you perspective when nothing else will. The second day, a tumbleweed blew across the interstate. I’m in a western movie, I said to myself, laughing. I found it so much easier to laugh now that this weight had been lifted from my shoulders.
