There were several different kind of oak leaves.
I am not sure what kind of oaks. Do you see anything you can identify?
The one below here is a tulip poplar leaf...I think.
This one a maple of some sort.
This one is a Ginko. Easy to id with an actual leaf right beside it.
Here is another.
I hope you are able to get out and enjoy some of this crispy winter weather and see some of natures surprises. Now it is time for that nap. Night night.
