The Keystone Indoor Drill Association is a competitive, educational indoor circuit. We have units in Pennsylvania, Maryland, West Virginia, Virginia, and the Washington DC metro area. The units compete in 5 disciplines; Percussion, Color Guard, Winds, Majorettes, and Dance Teams.

The Keystone Indoor Drill Association was formed in the interest of teaching the principles of good sportsmanship, fairness in all aspects, professionalism, and proper conduct under any and all prevailing conditions.
It is the desire of the Keystone Indoor Drill Association to promote better understanding among the units, good public relations, and above all, an atmosphere that is conducive to good clean competition.
While the Keystone Indoor Drill Association is truly an educational endeavor, it also teaches each and every member to demonstrate pride in their unit, their school, the association, and our nation at all times.
