October 1971 shifted the economy of Central Florida away from agriculture, military installations, defense/aerospace industries, and the NASA manned and unmanned space programs, and further towards tourism, service industries and residential development, the center of which is Orlando. But because of Sanford's former preeminence as a trade center, the city retains a significant collection of older commercial and residential architecture, on streets shaded by live oaks hung with Spanish moss. Its location on Lake Monroe and access to the navigable waterway of the St. Johns River has made it Central Florida's additional center for numerous marinas, allowing access for pleasure boats and commercial vessels to and from the Atlantic Ocean and the Intracoastal Waterway via Jacksonville and Mayport to the north. Jackie Robinson Sanford Field, built in 1926, was the location where Jackie Robinson first took the field in 1946 to play a member of a racially-integrated baseball team. In 1946, Robinson arrived at Daytona Beach, Florida, for spring training with the Montreal Royals of the Class AAA International League, a minor league affiliate of the Brooklyn Dodgers. Since the Dodgers organization did not own a spring training facility, training took place at several local baseball stadiums, including Sanford Field. Robinson's presence on the team was controversial in racially charged Florida. He was not allowed to stay with his white teammates at the team hotel, and many other local towns prevented the team from playing while he was part of the roster. The police chief in Sanford had threatened to cancel the game there if Robinson was to play. Robinson joined his team despite the threat, but the uproar from the mainly white audience in the stands caused him to be escorted off the field and he was not able to play. Historic Sanford Memorial Stadium was built in 1951 near the site of the old Sanford Field as the Spring Training Facility of the New York Giants. The ballpark is located just south of Lake Monroe on Mellonville Avenue, less than a mile from Historic Downtown Sanford. Other Major League stars have played in the Sanford stadiums, including Babe Ruth, Willie Mays, Tim Raines, and David Eckstein. 21st century Sanford was in the news in 2012 due to the killing of Trayvon Martin and the actions taken by the Sanford Police Department. A city streetscaping project began in 2004 as city leaders sought to attract new businesses and visitors
