history: I visited an underground cavern that was like 23 stories beneath the surface, i was uneasy to say the least.  I recently went to ruby falls_comma_ an underground cavern with a waterfall.  That sounds awesome. Have you ever been before? Not that particular one_comma_ no. I had butterflies in my stomach on that elevator going down 23 stories.
current: I wish I could go sometime that sounds like quite the experience.
next: Overall it was a good time, but i was nervous being that far underground, i need to learn to relax and enjoy things.
