I found stepping off the 100ft drop and swinging across to the other side to start the assault course suprisingly ok! I think that was largely due to 5 others going before me and witnessing them getting to the other side alive! This gave me confidence. Then the aerial assault course began!! At first it was really scary, but once I realised that even if I let go, I was still going to be hanging securely (albeit 100ft off the floor) in my harness, then I started to find the whole experience less frightening and more enjoyable. We all made it round, and by the end I was feeling really comfortable with the height.
I'm looking forward to trying rock climbing next....watch this space!
