If no one hears the tree fall, has it really fallen? In this case, yes. The tree split and fell some time this afternoon. Not sure exactly when, folks were home but no one heard it. Doesn't mean it didn't fall. It did. It will take some work to cut it up and clear it out. Fortunately, no significant damage (other than to the tree itself).
Good thing it didn't fall the other way. Our neighbors fence would have taken a beating!
