Here's a paragraph Scrappy wrote about our trip:
Mammoth Cave is really big. I had to walk down a whole bunch of steps to get inside. The walls were made of rocks. There were a lot of big puddles and pools. My favorite part was the Frozen Niagara. I was surprised that there was only a tiny waterfall there. It was mostly made of rock. I thought it was going to be like a regular waterfall, and maybe as big as Niagara Falls. But it was very small. It was cold in the cave. I had to wear a jacket. I didn't expect it to be that cold because it was so hot outside. I also saw cave crickets. They look kind of like spiders, except smaller. The ones that we saw were brown. I saw a giant spider, too. At the end, we had to walk across a giant sponge full of chemicals to wash our shoes. This is because of a special disease that bats can get. When we washed our shoes, we were making sure we don't spread it around to other bats.
