Shimmer Walls and tours of the old State Capitol just aren’t going to hack it: The Triangle Business Journal’s latest readers’ poll shows that what people want for downtown Raleigh is a sports and entertainment venue. The RBC Center, where the Carolina Hurricanes play, is halfway to Durham County. Of 942 people who responded to the survey, more than a quarter mentioned the sports angle, while 22 percent wanted another major business HQ to join RBC and Progress Energy. More impenetrable corporate buildings? zzzzzz…. Unless that major business would be a full-fledged grocery store, another item on the Raleigh wish list.
