Tennessee Truffles

I am currently trying to track down some Tennessee truffles for the winter menu. There is a company out of Tennessee that is currently producing truffles on a plantation in the Blue Ridge Mountains.

I hope that we can get our hands on some. It might be pretty hard, because they are pretty popular with big name cheffy-types.

Anyone know if truffles are found in Ohio?

I am also interested in trying "pecan truffles" which grow around pecan trees down south.
