IN 1948, ROY ACUFF BOUGHT DUNBAR CAVE TO BUILD A SUMMER REFUGE FOR WORKING FAMILIES — BUT IT WAS HIS WIFE MILDRED WHO CARRIED THE BUSINESS THAT MADE IT THRIVE.
By the late 1940s, Roy Acuff was already country music’s defining voice, headlining the Grand Ole Opry and packing halls across the country. Yet the singer wanted an outdoor gathering place where ordinary folks could escape the southern heat, hear live string bands, and spend an affordable afternoon together. In 1948, he purchased Dunbar Cave in Montgomery County, Tennessee, an antebellum mineral springs property just outside Clarksville, intent on transforming it into a modern recreational haven.
Natural cavern air cooled the property, pouring fifty-four-degree breezes out of the limestone opening into the muggy Cumberland River basin. At the cave’s mouth, Acuff built a massive open-air wooden dance floor, installed picnic grounds, and restored the adjacent lake for swimming and boating. The stage drew thousands of weekend visitors from Kentucky, Alabama, and middle Tennessee to watch Roy and his Smoky Mountain Boys, alongside traveling big bands and fellow Opry cast members.
While Roy provided the star power, the legal deeds and operational reality of the commercial park rested squarely with his wife, Mildred Douglas Acuff. Having already helped establish Acuff-Rose Publications six years earlier, Mildred possessed a rare grasp of business administration in an era when entertainment venues frequently ran on unrecorded cash transactions. She co-signed the property deeds, organized the operating budget, and ensured every supply invoice and vendor contract was settled on schedule.
To maintain steady cash flow during the intensive summer season, Mildred structured the park’s finances around predictable, multi-tiered revenue streams. She separated admission fees for the dance floor from bathhouse rentals, lake concessions, and swimming passes, allowing families of varying means to enjoy the grounds without paying a flat premium. Her rigorous daily auditing prevented the seasonal losses that routinely bankrupted rural tourist attractions, keeping the park completely self-sustaining through decades of fluctuating attendance.
Her presence extended far beyond ledgers and bank deposits. On sweltering Saturday afternoons, Mildred stood beside the main entrance gate, reviewing admissions and overseeing the food service staff to ensure meals remained affordable for working-class guests. While Roy warmed up his fiddle backstage, Mildred moved through the crowds, greeting factory hands, coal workers, and tenant farmers with genuine warmth that turned a commercial enterprise into a family tradition.
Her operational discipline absorbed the grueling physical logistics of managing a bustling resort, leaving Roy entirely free to focus on performing, touring, and fronting their creative pursuits. Under their shared stewardship, Dunbar Cave became one of Tennessee’s premier gathering spots, hosting national radio broadcasts and community square dances that defined post-war leisure across the Mid-South.
The Acuffs maintained ownership of the property for nearly twenty years, keeping it solvent and active until its eventual transition toward becoming a preserved state park in the 1970s. The site remains a protected natural landmark today, celebrated for both its prehistoric cavern archaeology and its mid-century musical heritage.
Roy Acuff spent his lifetime standing in the center of the spotlight, celebrated as the King of Country Music by generations of listeners. But outside the glow of the footlights, the community retreat that gave thousands of working families their best summer memories survived because Mildred kept the enterprise grounded, capable, and true.
