My son usually shortens that to West Laf (where Laf is pronounced as lawf). One fun thing to do there is stopping by XXX for a great root beer.
The mistake that was made was to say SubTropolis was West of KC vs NE of KC.
So who said that Springfield and KC was close together?
Well, go east from KC to Quincy IL for another limestone cave outfit with rail and barge access:
XXX in West Lafayette is an excellent diner.
Any other underground locations? I knew of KC and Quincy, but not Springfield.

Not as big, but more high value is Iron Mountain’s facility near Butler, PA.
