[Alas Babylon!]

For a REALLY scary caving story, read:

LONG read but good!

[Qiviut]

"The passage was so narrow that whatever position I started with I would have to stay with through the entire length. There was just no room to move around or change positions. I would also have to turn my head one way or another, and keep it in the same position. This crawl was TIGHT!"

I'm breaking into a sweat reading this .... my worst nightmare!
