In reply to JimR:
I did some work for a lovely 'upbeat' lady a few years ago. When she found out I was a climber she told me about her late husband who had also been a climber and had done first ascents in the Alps etc when he was young. In later years he had done more sailing. She said he wasn't daunted by anything and would just go and 'do stuff' if the idea came into his head. I had a great chat with her about her husbands adventures and I remember thinking he must gave been quite a guy!
Your post has just rekindled these memories as it turns out I was chatting to Jeffrey Allisons widow! I always meant to read a bit about him and your post has reminded me. Thanks for posting.
