BONNER SPRINGS, Kan. (AP) — The leaders of the National Agricultural Center and Hall of Fame in Bonner Springs are trying — again — to figure out how to ensure its future. The hall closed for the season in May because of financial troubles, the second time in five years that's happened. Only two part-time employees and several volunteers work there but a dedicated board is determined to make the hall relevant again. The 160-acre facility is the national hall of agriculture. It has separate museums and many exhibits that give an extensive history of farming and agriculture. The Kansas City Star reports that the hall's board of directors is searching for ways to get younger people involved in the hall and to update its technology and exhibits — all without any government funding.
