"Sky's the limit for 5 year-old hiker"

Last summer as I was descending the Pfeifferhorn, up came this little girl and her father, a man who spoke with a foreign accent. "How old are you?" I shouted across the South face. "I'm six", she sent back (I think the article has the incorrect age), and then added, "I hiked up here when I was three." I did in fact say something to her father like "I wish my boys would come up here with me."
