P.S. I recommend reading the comments. You won't be sorry.

Cool, I never even knew that these things existed. The Superman comic is neat!



If you have a problem, if no one else can help, and if you can find him, maybe you can hire... Tunnelrunner33!

Wow, that's pretty cool. Does anyone have pictures of some from their own explorations? Or perhaps a photo of one in operation? I think the article said that there are a few still in operation in the Rockies.
