its so sad and i really feel for his family and for the ones who had to leave him behind, that mustve been soul destroying! But it makes you think why on earth people feel the need to climb these mountains whaen the risks are so high and that all they get for it is a photo at the top.
when i climb the mountain behind my house, my reward is the pub at the top of llanwonno.
I'll have you know - i have to fight sabre tooth tigers / wrestle crocodiles / swim in shark infested waters / avoid women drivers putting on their make up while driving .
