Congratulations to Intrust Bank Arena for ranking 17th in the nation and 39th in the world in ticket sales during the first half of 2010, according to Pollstar magazine. That's quite a debut for the Sedgwick County-owned facility, which has only been open since Jan. 9. Who knew Wichita could sell more seats in six months — 135,751 total — than Omaha's Qwest Center and Denver's Pepsi Center? And Intrust Bank Arena hosted 10 of the period's top 20 acts in the United States, including No. 1 Bon Jovi, No. 3 Taylor Swift and the No. 5 bill of Reba McEntire, George Strait and Lee Ann Womack. But it's best to temper expectations for the rest of the year: These are sobering times for the national concert market, which saw a 17 percent drop in business the first half of the year. One likely reason showed up in a new Rasmussen Reports poll: 70 percent of adults think concert ticket prices are too high.
