November 17, 1960: "Rice Parish, 82-year old resident, climbed the Lanagan forestry fire tower recently and it was his own idea, reports Leon Lichterman, district forester of the Neosho district. The elderly gentleman was accompanied by his son every step of the way but needed no help. 'Apparently, Parrish wanted to do something different from the ordinary rocking chair routine,' Lichteman commented. The 120-foot steel tower is one of 89 lookout towers scattered through Missouri's woodlands which many thousands of visitors climb each year to view the scenery. 'But few visitors are in their eighties, and many a younger man has refused to go to the top,' the forester said." (The Wheaton Journal)
