Farmer's Market, Falmouth, Cape CodBeen wandering in the flesh-pots of Cape Cod and Long Island, with a side trip to Boston and the MFA there. Chihuly, the extraordinary glassmaker was having a major exhibit. Check it out at http://www.mfa.org/. As you can see he has completely solved the water problem. Cape Cod is basically one big fish-hook shaped sandspit. God knows how the Pilgrim Fathers managed to grow anything at all. The Farmer's Markets on the Cape have beautiful lettuce, kale ( learned how to cook), herbs, peonies, rhubarb and lots of stuff for tourists to buy- lobster buoys,straw hats,fish prints (some very good) and lighthouses for your refridgerator.
The North Shore of Long Island, on the other hand, is still farm country once you move away from the coast ( wall to wall summer houses, mostly very opulent-think Malibu on steroids --- but you already knew that.) There are vineyards looking very prosperous, fields of potatoes and other edibles.
Small fishing is still viable --clams, mussels and lobster as well as lots of fish-haik, sea bass, flounder.
