Winds of Change

It was 2am, a few weeks ago, when the winds arrived, thrashing the trees and thumping against the window panes. 35-40 mph gusts threatened to peel shingles from the roof.  The sounds of branches snapping and debris hitting the house made it impossible to sleep.   The Wizard of Oz popped into my mind.  I wondered what was blowing out and what might be blowing in?
