(Photos from my personal travels)
There's something about trees and roots that has always fascinated me. Is it because every tree is like a person ... unique? Is it because roots grow underground and create stability (mostly)? Is it because they have roots and often I feel I have none?
Try this, an exercise in creativity:
Look at the photos, choose one that "speaks" to you, give it a name, and describe its personality. Do it again with each one if you like.
Have fun with this, you may even find characters to put in your stories.
