I was taken there when I was six, an age at which I was impressed by everything. Lookout Mountain was great, Rock City was a hoot and the train thingee was a blast.
Ruby Falls on the other hand was a walk through miles of dark tunnels, where the only sight I saw was the charming view of the rather large butt of the guy in front of me, with the end result of seeing a trickle of water come out of a cave wall.
Needless to say, I was underwhelmed by the experience.
Same here. Saw all of those. Did the trip also include Wonder Cave?
