can fine oysters from hundreds of places from around the country and beyond. now if you think all this oyster slurping is nothing but a fad -- consider these thoughts from rowan jacobson. >> when you pick up an oyster you are kind of reliving this very early experience of humanity, which is eating a raw animal live out of its shell. an oyster is live up to the moment you shuck it and after you shuck it, it's unclear how dead it is, right? so you're doing something that is definitely not a party of normal, you know, civilized life. and there's an intensity to that experience. you know, it's just like one-on-one, you and the oyster. >> reporter: and as more and more americans experience that rush, oystermen and women can't keep up with demand and prices are higher than ever. but today's story of the north
