One of the scariest activities we had in grade school was the rope climb. It was just a plain knotted rope hanging from the ceiling above a one-inch thin mat. I don’t know why they tortured 6 year old kids with such a feat of strength and fear. I think to “pass” the activity you had to get both hands above the second knot. There was that one kid though who was bigger than everyone else, already had a mustache and a few scars. He climbed up that rope like he was casually pulling a kite down from the sky. His children will never have a hard time picking him out of his grade school class photos.
