We visited Endless Cave in Cave River Valley. Only 4 of us ended up going, but we still had a good time. Most of the time we were walking in stream passage, but there were some short stream crawls. We never found the formation room we were looking for, but it was still a fun trip. We were in the cave for about 3 hours.
On the way home we decided to take the exciting way out of the valley, through a stream, through some mud, and up a washed out dirt road, but that didn't work out too well. We got stuck for about an hour. I guess my Explorer is meant to stay on the road.
