An interesting trend lately--speaking of the urban/rural split--is the "locavore" movement. Basically environmentalists who believe that they should eat foods that are available locally. A fair number of them are taking up hunting, recognizing that the game they shoot is "organic". And a lot of them are involved in the reverse flight: urban to rural, because it's easier for them to raise/forage/hunt/fish in the country than it is in the city.
