Barbados celebrates Independence Day. It became free from Great Britain in 1966; however, it has remained in the British Commonwealth. This easternmost island in the Caribbean is 166 square miles, about 2.5 times the size of Washington, DC. In the colonial days the economy depended on sugarcane. Today, however, tourism is a big source of revenue. Almost 300,000 people live in Barbados, and close to half the population lives in Bridgetown, the capital.
