I should have run this morning but we are staying in a really lovely B & B and I was enjoying being asleep, so I stayed there. Then we had a really fun day taking two tours of Mammoth Cave. The Historic one was alright but the Domes and Dripstones one was really excellent - a crazy descent down lots of stairs through a vertical shaft, and then some great stalactites and mites at the end. Two real characters of tour guides too. Really fun!
