It promises to be a bright weekend in a dark cave as two days of entertainment are planned this Saturday and Sunday at Cumberland Caverns. The music begins Saturday at 2 p.m. when Cumberland Caverns Live and Security Federal team up to offer Celebrate McMinnville, a community gathering that recognizes the importance of keeping music in Warren County. Admission to Celebrate McMinnville is $3.33 to coincide with the concert venue at Cumberland Caverns, the Volcano Room, being 333 feet underground.
