My favorite crawl was The Corkscrew in Midnight Cave on one of my early trips
to CV. I didn't find it a particularly hard crawl except that I got a little
claustrophobic. But what made it stand out in my mind was that someone (don't
remember who) had taken their speleopups into the cave. As I was making my down
the crawl, I heard some noise behind me and four furry feet planted themselves
in the middle of my back and a speleodog went right over me and out of the
crawl. Guess he didn't want to wait while I made my way down.
