Popular festival exhibits typically showcase bizarre items, such as outlandish culinary conceptions or White House replicas built from unmeltable snowflakes. Absorb eccentric creativity with today's Groupon: for $20, you get two tickets to see either Village People on Friday, June 17, at 7 p.m. or Ricky Skaggs on Saturday, June 18 at 7 p.m. at the Secret City Festival in Oak Ridge (up to a $40 value). Gates open each evening at 5:30 p.m., and concertgoers must provide their own seats. Admission to the rest of the festival is free.

A two-day spree of exhibits and performances, this year's Secret City Festival hosts outdoor concerts featuring Village People and Ricky Skaggs. Disco-era icons Village People perform spirited hits such as "Macho Man" and "YMCA," which have instigated more dance-offs than gang violence and British Parliamentary debates combined. Village People follow funky rock n' rollers Dishwater Blonde, a regional act that lays down agreeable grooves.

Fourteen-time Grammy Award winner Ricky Skaggs closes out the festival with bluegrassy bebop that thrills toe tappers already dosey-doing to the sounds of opening country act The Springs and Greylan James Band. The Secret City Festival also features day-long activities open to the public, including educational exhibits, festival food, and an elaborate WWII reenactment complete with authentic amphibious Terminators.
