Nice photos.
Mother Nature (or who ever is in charge) really knows what their doing.
Every leaf (on a tree) looks the same / year after year.
Did you ever look at a leaf as it was decomposing ?
It has a skeletal structure to it, quite amazing.
Tree trivia: The Ginkgo tree is one of the oldest living tree species.
It's leaves have been found along with dinosaur bones.
A lot of Cities will plant Ginkgo trees along their streets because they are very hardy (time tested).
You could pick up a leaf off the ground and write a whole book about it.
It won't be a best seller, but their is a whole lot going on there.
