I've never felt anything like it. You're a few metres off the ground, standing on one leg balanced with your hands and reaching as hard as you can with your other foot. You've got a rope, you're not going to fall... but it's so real. Reaching the top I realise there was music on and people around and all the rest, but my mind has been blank, completely on the moment. In the moment. It feels fantastic; I was shaking (although later because I was over-reaching and just got fatigued). I want to do this again.
