thanks for all the replies... i think it looks pretty sweet too.

aric, the smokies is the reason i was actually first looking at mammoth caves. i was checking to see how far of a drive it is - unfortunately its too far for this trip! mammoth caves is going to be 8 hours away from me to begin with - the smokies would tack on another 4 at least. i went there a couple years ago though, so i definitely agree with you on that one.
