CHATTANOOGA FALL (en Inglés) - Boyd Craven Jr.;LA Bayles;S.M. Schuster

Anna's colleagues from Sullivan Realty in Chattanooga, Tennessee were to attend a team-building event, sponsored by their boss, Keith Sullivan in the caves of Ruby Falls, deep within Lookout Mountain.

Their private guided tour was to begin at the elevator beside the gift shop inside the main building at 12:45 p.m. on Friday, October 28th.

Emotions ran from excited to terrified as the long elevator ride took them 1,120 feet straight down to the main cavern where their 45-minute guided walking tour to see Ruby Falls began.

All of their senses were overwhelmed by the beauty and the power of the falls as they arrived, just in time for the lights to go out and a terrifying rumble began...

Don't you dare miss the terrifying adventure that ensues!
