I always thought caves were pretty interesting. They are large stone holes in the ground made so many years ago; inside are tons of secrets and creepy stuff.
I say creepy because most of the time caves are dark, and animals hide in them. And in movies, caves are always portrayed as the secret den to a monster of some sort.
I do respect caves, though; I feel like they need their own space. What I mean is that I never want to be a spelunker or anything like that; the whole idea of squeezing through super tight spaces made of a one thousand pound boulders? No way. I freak out if my shoes are too tight. So I know I could never do that. That is why caves can be creepy. They hold so much mystery and history (that rhymed).
So I think caves are awesome and are beautiful, but I also definitely think they can be creepy.
