I recently found out about this really cool rock climbing/trail like 5 minutes from where we live. And, it looks over the Cumberland River. I am trying to be better about taking the kids out of the house to do things and get some fun exercise. So, we tried it. It was very steep. And I did freak out quite a bit about the kids possibly slipping off and rolling down into the river.....yea, I'm a scardy cat like that. They loved it, though. We can't wait to go back many more times.
