I am thinking of a crazy spontaneous trip to Florida around New Year's Eve. Air fare is way up there, so I thought it would be fun to drive. I want to make it more of an adventure. What are some really fun spots along the way. I have two boys - 14 and 9. I am thinking Mammoth Cave, Ruby Falls, The Varsity Hot Dog place in Atlanta, any other good ideas? Looking at doing each way in 2 days........ thanks!!!!!
