Truffles in North Carolina???

Apparently this is old news, but this is the first that I had heard about it...black truffles can be grown in North America and, more specifically, North Carolina. It's a pretty good cash crop but takes 5-7 years to fruition. It's interesting but surely not an easy task as noted in this article. The leader of the pack is Mr. Franklin Garland, whose website boasts a wealth of information.
