After coming out of the Commencement Concert at Sprague Memorial Hall at Yale University yesterday my neighbor and I heard another sort of music. Naturally we RAN over and to our delight we saw the Carnaval de San Francisco Tetlanohcan happening on the New Haven Green. Dancers of all sorts! Dancers, called charros, were dancing the Los Charros. Tetlanohcan is a small village of 10,000 people and it's in the Mexican State of Tlaxcala. Tlaxcala is the smallest state in Mexico.
