Staff gave us a safety briefing prior to letting us loose. He said, "most of bouldering is falling" as he warned us to stay well away from the walls!
As I did last time, I headed for the children's wall. It has more handholds and crawl spaces. Also much more noise. I'd forgotten that as well as my earplugs! The kids were a little slower on the wall than adults upstairs. I just waited for another child to make the climb to add to each sketch of a climber.
Next I joined the line of sketchers on the second floor balcony to sketch the climbers from above.
