A donor left $6.85 million to nine groups and organizations in Milford, Neb. (population 2,156), including a $1 million endowment for maintenance and improvements at Thornridge Golf Course, plus $250,000 to establish a permanent retirement fund for John Melena, its Superintendent. Melena, 51, says he doesn’t plan to retire anytime soon and that the nest egg will be used for future superintendents once he does decide to end his work at Thornridge.
