Ticket sales at the Des Moines Civic Center don't just fill up seats. They also earned the organization the distinction of a No. 28 ranking, according to information provided by the Civic Center. The ranking comes from Pollstar, a concert industry trade magazine, that each quarter ranks the top 30 theaters with fewer than 5,000 seats according to number of tickets sold. So far this year, the Civic Center has sold 120,827 tickets.
