Ok...I'll post a few each day. First up, Mammoth Cave:
We did two different tours in Mammoth Cave. The first one was a lantern tour that lasted for 3 hours. It was very hilly. By the end of the day, I had 16,700+ steps. Since it was so dark because of the lanterns, I was only able to take pics on our second tour. We were not allowed to use flash photography in the cave, so the pics are a little dark.
Just a little Gee Whiz info...so far, there are 435 miles of Mammoth Cave that have been officially mapped out. The work is not complete.
