Today I went to brooklyn boulders in chicago. It is a climbing place with lots of huge climbing walls. I had to used the auto belay to climb the walls.I climbed the 30 feet walls but there were 60 feet walls which needed belay lessons. BKB (brooklyn bulders)also has a big gym with lots of machines like tredmills a stationary bicycles,and a yoga room.The gym has weights,stretching machines,and a tightrope to walk on.My mom and me got a daily pass and stayed there from 10:00 to 13:30.There were lots of bouldering walls with a cave.(no harness).Brooklyn Boulders measured the difficulty by a code and numbers.I went to 7-11 for lunch.There was table tennis and a throwing game there too.It was a fun day at Brooklyn Boulders.
