Before "Frankenstorm Sandy" knocked down some neighborhood trees and blew most of the leaves off the rest of them, we had a day with a mackerel sky. Never having seen a live mackerel, I must trust that the large school of cloudlets swimming in unison over my head really do look like the spotted scales of their piscine namesake. The sun illuminated the orange and yellow leaves while the pattern of white and blue moved swiftly from northwest to southeast. Paul McCartney's song "Calico Sky" played in my head. I was thankful for such a beautiful day and such a remarkable sky.
