Oh gosh imagine running into a big person, it would be like running into a rock. Stuck underground, I think like some people have a fear of being closed in and won't be buried in a coffin.
I remember going underground to coal mines when I lived in Wales, that was quite an experience as you are walking along tunnels crouching, strange feeling, so I get you Super Eli!

Yes add it to the list, it is a wonderful sight to see:)
