Mammoth Cave Grand Avenue

This was the all encompassing four hour tour of Mammoth Caves and covered four miles of the cave open to the public.  It was fast paced and included about 600 stairs, ramps and slot canyons.  It was awe inspiring and worth every minute. There were even two bathroom breaks along the way. Imagine that, bathrooms at 300’ below the surface.  Someone asked what they do with the waste—it gets pumped out to the surface.
