We never did anything CLOSE to this cool in my gym class. Kids at a school in Chicago got to run an obstacle course the other day, where they had to climb a huge mountain of milk crates.
A video of it is blowing up on Twitter, because one girl had a pretty rough run. Whoever was working the rope attached to her safety harness yanked too hard . . . lifted her up off the ground . . . and she crashed into the milk crates headfirst.
