i gots to pay £15 for registration which i dont mind at all cos i get to DO something and the money goes to charity

yes -
- raising money for a new ambulance, do something good etc
-it's an experince and would just be a pretty cool thing to do

no -
-im scared of heights
- im scared of heights and im worried i'll sign up and then just not do it once im up there
-probably be a bit embarassing, peopel will look and i'll look like a wussy, lumpy doofus

...but i really want to.
