The fragrance of lilacs is unmistakeable. They are blooming next to the old caretaker’s house at Radnor Lake this week. The state naturalists take care of Radnor Lake, now, but there used to be a caretaker when the lake belonged to the L&N Railroad. Radnor’s website has a charming remembrance of the McElyeas by their granddaughter, in which she tells of her grandfather arresting illegal fishermen and handcuffing them to the porch rail until the sheriff came for them. If they were there at breakfast time, Mrs. McElyea would feed them right along with her own family. Presumably, in spring, they would also have the benefit of the wonderful smell of lilacs blooming beside the porch as they waited.
