En Route Options?
 

So I'll be driving from St. Louis, MO to St. Simons, GA for work, I was wondering if anyone between both those places had any recommendations for driving roads? I only will have two days of driving to get there so I'm looking for route options that will be a fun drive without going too far out of the way. Also, I'm putting new exhaust on tomorrow so if there is a decent tunnel that would be great too, trying to get some new video/sound bites.
