Blues aficionados Lori Ragsdell and her husband, Charles, have brought blue sky to blues events in Eureka Springs and beyond. The Eureka Springs Blues Weekend is an all-volunteer fundraiser for Turpentine Creek Wildlife Refuge and the Blues Foundation's HART fund (www.blues.org). A full-time senior executive with a Kansas City insurance firm, Lori, with tireless effort and selfless ease, embroiders the endless details that make the Blues Weekend a success. Without playing a single note, Lori has earned a reputation as an unsung legend in the blues world. This week a choir of big cats and performing artists-in-need join the chorus in singing her praises.
