Debbie and I took my son and grandsons up to inner Space Caverns in Georgetown yesterday. After a brief but filling stop at Whataburger, Chip drove us up to the caves. We arrived just in time for a tour, and headed down, down, down the long ramp into Inner Space Caverns. We had a pretty good tour guide, he shared lots of details about the things we were seeing, and or course we got the total darkness experience as well. Overall, it was pretty fun, and the boys certainly enjoyed it.
