A Secret Little Spot
The entire base of the tree is hollow. Not being a tree expert, I don't know if it grew that way, became hollowed out over time or was cleared out by animals or bugs. All I know is that it now has this special trait that separates it from all the other trees in the woods.
You can tell when you get close that it has been home to many generations of ... something. It's fun to think about lots of babies being born in that tree, it being used as a safe haven from predators and a lovely place for a summer's afternoon nap.
