National Doughnut Day is Friday and shops across the D.C. area are celebrating with free goodies and deals.

National Doughnut Day began in 1938 by the Salvation Army in Chicago as a way to honor the women called “Doughnut Girls” who delivered tasty treats and assistance to troops during World War I — all while dodging bombs on the battlefield.
