Today is Day 101 of the Papa’s Walk Challenge!  

It was cool, sunny, and breezy on my walk today. About half way through my regular route, I entered a block lined with sycamore trees.  The first thought that popped into my head was, “All the leaves are brown.”

It’s as if the trees got the memo that Autumn arrived and the chlorophyll (green pigment) receded from the leaves and back into the stems and branches of the tree on cue. (Click here to learn more about why fall leaves change color.)

Of course, my thought that, “All the leaves are brown,” triggered my memory of the song, “California Dreamin’“ by the Mamas and the Papas – and now I can’t get the song out of my head!
