I'm glad you started this thread - indeed he is.
Did you know that they did their planning and training in North Wales and stayed at the
Pen-y-gwryd hotel at the foot of the Llanberis pass? It still has a lot of memorabilia on display there and the ceiling signed by the expedition members.
If you stay there and take the kids up Snowdon, when you get back they have a little ceremony where the kids get to have a drink from a cup used by one of the expedition members (I forget which one) and they get a badge and a little certificate.
It was and still is, the place where they hold their re-union meet every now and again. Last time I was there the owners told me it's a rarer event now than it was and sadly, there'll be one more missing from it.
