Here is a Pterocarya fraxinifolia or Chinese wingnut tree. It is only a five minute drive from our house.
We measured it's circumference. 32 feet! Just a massive tree. Perhaps the largest in eastern Canada and NE of all the Americas.

Seeds for this tree were brought to Great Britain around 1800, then here thereafter. So this tree is no older than around 210 years old.

Here is a video from our last visit to the tree.
