Papa.org operates a facility in Pittsburgh that is probably the biggest collection of modern pinball machines in the world. PAPA holds two events per year that are open to the public. On March 28-30, 2014, PAPA will hold a match play tournament called Pinburgh. Even if you do not compete, the majority of the machines are available for play during the tournament. It is a great opportunity to play almost all of the modern machines and watch some of the best players in the world compete. I have put it on my calendar for each of the past two years, but have not been able to make it. Going to try to get there for the first time this year.
