Apparently chestnuts are growing in popularity and make a good addition to a small farm. I didn't know this, but we're one of the few countries that doesn't consume chestnuts as a main staple in their diet. Other places eat them the way we do potatoes, even going so far as to make flour with them (I did know that).
It's interesting to me that there are sooo many crops farmers can add, with just a little imagination.
The article that I found that info on was on Hobby Farm.
