Last Sunday [October 4] was a dreary day in the Nation's Capital, but it was immediately brightened and made better with the Cochon 555 Heritage BBQ event at Union Market. This culinary competition, which is part of a five-city exhibition tour across North America, has three goals:  (1) to promote and educate individuals about heritage breed pigs (2) to highlight grilling cultures from around the world and (3) to raise funds for a local cause.
