A planned birthday surprise for the Mango Musilini. It's also Flag Day. ' It also marks the 250th anniversary of the U.S. Army. The parade, which will feature Army equipment, flyovers, musical performances and thousands of soldiers in uniforms from the past and the present, caps off a week of programming designed to celebrate the country's military might.'. A perfect time to create another 'incident' to devide the country even more.
