up here in northern california's artsy craftsy humboldt company to make some bean-to-bar chocolate. the creation of adam dick and dustin taylor, a pair of brainy former carpenters who seem to know a little bit about a lot of things. what kind of birds are these, you know? >> those are, not sure. they might be dog woods, but my knowledge of birds is lacking. >> here's the thing in tv. if you speak with certainty, your credibility will go through the roof. no one will question you. you could say pop rants. you could have said it. why are we talking about birds on the way to the chocolate shop? we're driving through a bird sanctuary that happens to be a sewage treatment facility. this being humboldt county, it's been given the title interpretive marsh. yeah. we're going to talk about chocolate at a sewage factory.
