Whenever I travel, I always opt for the window seat so I can enjoy the scenery.  But for most of this flight over the U.S., thick clouds prevented me from seeing the terrain below.

So I decided to look at them instead of reading or snoozing.

Each time I looked, the pattern and thickness had changed.

Finally, it covered the land below.  And I remembered the line, I really don’t know clouds at all, from Joni Mitchell‘s song, Both Sides Now.
