I envy you and dont envy you at the same time Hodgy! When i was younger i had no probs climbing and hanging from heights but now not so much. A couple of years ago a bloke up in a fire tower invited me up and half way up the ladders i called up, I'm gonna leave it mate. I was sh!tting bricks. But he didnt hear me so i took a few deep breaths and pushed on up just taking one ladder at a time. White knuckles!! Got there but not for me any more now.
