The first thought that sprang to Sarah’s mind as she heard the thunderous rumble was "freedom!" She was nestled into her favorite armchair with a good book. She jumped up and practically skipped to the window.

The enormous tree that had blocked her view for years was down! A rush of exhilaration coursed through her. Now, she could see the entire valley.

The thought of the unobstructed sunsets, the expansive views, caused her to feel lighter than air. She grabbed her binoculars and rushed outside, laughing. This was the start of something wonderful.
