This is an old post that was experiencing technical difficulties and never made it up. Inner Space Caverns is in Georgetown, about 30 miles north of where we live. Mom and Dad made a trip up there based on the cheesy sign and they were very surprised and impressed. It was huge!!!
Inner Space caverns were discovered in the 1960's by a Texas Highway Department drilling company. After drilling through 40 ft of limestone, they discovered the caves along with lots of old fossils and crazy formations that took a looong time to form. This is the entrance to the cave. You have to take a little railroad-type car to get down into it.
This is one of the bats that live inside the caves. Mom said she was scared when they would fly around everyone's heads.
Just to give you an idea of the size of some of the cave rooms, that's mom in the middle of the picture!!!
