Where Have All the Leaves Gone?

What happened to our leaves? I noticed on Wed. that the trees still had many of their beautifully colored leaves. Then it was like someone threw a switch and the leaves fell off all at once. Our backyard looks as if we have had a leaf storm, dumping 6 to 8 inches of leaves. Fire up the leaf blower and make a pile that we can burn. Or wait until the wind blows them away. When we choose that method, we are not very popular with our neighbors. But then I don't see our neighbors from the west scrambling over to our place to retrieve their leaves.

Before the leaves fell, I took a picture of our burning bush, fully ablaze in red. Hope you enjoy it as much as we do.
