Ever since I went on my first cave tour a kid, I have been fascinated by them. They're almost otherworldly, yet they're right under our feet. The temperature drop and the pitch-black darkness are creepy, yes, but when I look at the formations and realize how long it takes for stalagtites and stalagmites to form, the creepiness factor turns into one of scientific wonder for me.
In my early teen years, I was lucky enough to visit Carlsbad Caverns in New Mexico, and that was an awe-inspiring treat. There was one point where we were exactly a mile beneath the surface of the Earth, and we could make phone calls from a special phone booth to tell people where we were. There were also chasms next to the man-made path that our tour guide said could be miles deep, as they'd thrown things down them and never heard them hit bottom.
Other people find caves as frightening as they do fascinating. For example, I have seen the movie The Descent, which scared the hell out of me.
But I can assure you, in Roads, the cave scene is much more fun and romantic. ;)
