Seriously though...
One of my meetup groups went to one of those indoor rock climbing places. We did 3 lessons for $20. It was our first time. We used the shorter wall, but our arms were dead by then, particularly the forearms. We all had a lot of fun, though a little scary when I slipped a couple of times. Adrenaline was definitely pumping.
But I enjoyed myself immensely (despite my issue with heights).
