State business leaders are coming to Pella for a three-day convention next week. Ann Frost with Visit Pella says the Iowa Economic Development Authority is holding its annual conference in the Tulip City for the first time. Frost says this is not only important in terms of networking, but a chance to showcase what makes Pella special to those who make key decisions on grants and other government programs supporting tourism and development. The three day conference includes events at the Pella Opera House and Central College, and tours of many local businesses and organizations.
