At the Kroc Center, after we swam we went and did the rock wall. It was so cool! We had to put on a harness and then they attached it to a rope. The rope was connected to a round thing up at the top of the rock wall ; it worked like a pulley. I climbed up to the top of level 1 and level 2. I almost finished level 3 too. It was so fun!!!!!!!!!!!
