I haven't watched that one, will have to look it up. I am guessing ancient wood, makes amazing wood floors and doors for those that are will to pay for it.
We have a camp (lake house) in the swamp near Lake Verrett where Troy's portion of the show is filmed. It's a really gorgeous area and we love going there. My husband met Troy at the bait shop his family owns and said he is a super friendly guy. We're going there this weekend so I can take some photos of the gators. If I get some nice pics, I'll post them.
OP, I guess it's to each his own because in general I will not watch reality shows or those singing or dancing contests.
