Reminds me of the enormous room in Borneo that is so large a small
airplane flew into it.
Here in the USA, the largest room is in Tenn. called Camps Gulf.

Interesting, I didn't know that! You probably have a working knowledge
of those guys that started in a small cave somewhere around Cave City,
KY and ended up in the what was then the dining room in Mamouth Cave.
Really interesting (to me) story.
