I just talked to my father for a while on the phone. As you might remember, my father is a lobsterman in Maine. He has his own boat and a few hundred traps; this is pretty much how he makes his living. Anyway, currently lobster is selling very cheap because many people consider it to be a luxury food. It occurs to me that "the lobster index" might be one way to gauge the state of the US economy. I don't know if lobster is a "lagging indicator", but for my father and most of the people on his island, it is pretty much central to the economy.
So, currently the going price for lobster is $2.75/lb. I will update if the price goes up or down. I'll also note that, for those of you who like lobster, it is possible to get it for about the same price as hamburger currently.
