Natural Bridge Caverns, a Texas Sized Cave

Hello, people of blog land.  I'm here to share a little of my Texas with you, today.  In a quick day, trip, we drove over to San Antonio to visit Natural Bridge Caverns.  I have not been since I was a girl, but couldn't stand another moment on the sofa during our school break.  This cave was a nice reprieve and hard to believe such beauty exists just under the Earth's surface.  Take a gander...

At the entrance you see the name sake "natural bridge" resulting from a sink hole.

Dark discoloration, remnants from bats who occupied the cave thousands of years ago.
