Any one here ever been to mammoth Cave in Barren County Kentucky? i was just there today. took the six hour tour and went pretty deep. there are fish down there that have Evolved to have no eyes. real creepy looking. and halfway down they decided to do a lights out and turned all lights in the cave OFF talk about dark. like i couldn't see even an inch in front of my face. but anyways best day ever. very glad i wore a diaper down there too as there are no bathrooms and its a three hour hike down and three hour hike up. after that a changed myself then went back in for a diffrent 2 hour tour. that place is amasing wish i could have snapped pics but there was no Flash allowed due to bats. and there was very little light.
