Several clubs stopped their IDPA matches in the last couple of years.
The nearest to Pittsburgh are the matches held at the S.T.A.R.T. facility in Mingo Junction Ohio (just inside the Ohio line) and the two in West Virginia; Hancock County Sportsman Association in Weirton and Mason Dixon Rifle Club near Morgantown.
Check the IDPA websit and go to the club listing section for more details.
Hope this helps.
Tomorrow's battle is won during today's practice.
