Nice park. When I was a kid, there were some cliffs made of sandstone. We know all about sand stone. For instance you could write you name by scratching it with a sharp item. During those times, kids would write things such as 'so and so likes so and so', or a heart-- those types of things. But the main reason I am writing is that those darn cliffs are just the very thin out crops of a ledge you would have to walk on. Hey you were a kid and you saw some one else do it, so you had to try yourself. Scared the life out of me!
