American chestnut was the redwood of the east. Its damn shame it is not thriving
We have one here planted in the 1970's that towers over my house and had one next to my childhood home. It's amazing they do as well as they do, but the concern now is genetic bottleneck since most of the seeds planted worldwide were from a few trees, so the successive generations I guess don't do as well as the ones in that valley do.
Other than the squirrel issue I have that was resolved, the tree is a lovely tree and I have had many dreams of them and memories of sitting in the shade under them with my cat as a kid. It doesn't throw sap like a fir does and the branches are thinner and unlikely to cause major damage to a house if they do come down.
