Lost River Caverns-It's 95 degrees and humid-What to do with the Grand kids-take them to a constant 52 degrees-a cave!!

The cavern has an underground "river" -the interesting part is they never could find where the water exits.  They tried dyes and other markers-nothing???

Another interesting point is the water level-this year we have had a lot of rain.  They have pumps running full time to keep the cave passable.
