Listed in 1,000 Places to See Before You Die, Greenwich is unique, in that it is actually two concours, back-to-back. Saturday’s Concours Americana is exclusively for American makes, while Sunday’s Concours International is exclusively for imported marques. The Greenwiched based 12-M Yacht Development Foundation will again have a modest display of former America’s Cup 12-Meter yachts moored at the Delamar Hotel. Given good weather, they will engage in match racing during the weekend. Concours visitors will be able to view the yachts up close, and there will also be limited opportunities to sail on them. Classic motorcycles will also be on display.
