    so it’s not hard to feel great awe when you see some caves like this ‘conquered’, knowing the effort it must have taken :-)

    Mammoth Cave isn’t “conquered” – not by a long shot! They explored eight more miles of it for the first time just three years ago (and have apparently added six more without making the news since then, since the total is now 426), and estimate there may be another 600 miles yet unexplored.
