Share 'Cigar box guitars featured on Michael Waddell's "Bone Collector"!'

Yesterday, on the Outdoor Channel, they gave a mention to CBG's.  On Michael Waddell's show, "Bone Collector", they met someone named Mark, that build's CBG's.  Did anyone else see the show?  Does anyone know Mark, the CBG builder?  Is mark a member of CBN?  If not, and someone knows him, he should be invited to the group.
