I know of at least one additional American chestnut tree not listed in this article, in Oak Glen, CA. I was apple picking there and met a wonderful old man from Brittany who made a pilgrimage there every year to pick chestnuts for traditional dishes. It was sad to hear from him that in his youth chestnuts grew in abundance, but today they are few and far between.

The chestnuts themselves are tasty and very fun to gather, with their interesting and spiky seed pods.
