First time was in about 1971/2 as a young lad, trailing exhaustedly after an ex SBS Royal Marine Commando, who although in his 50's (as I am now!) could still put in a good day in the hills.
Second time was via a 670ft v.diff rock-climb 'Avalanche Buttress' - on a Craig yr Ysfa, a remote crag at the back of Carnedd Llewelyn. We completed the rock climb up onto the top of Llewelyn, before traversing the range and descending to Ogwen, from Pen yr ole yr wen.
"Got tight last night on absinthe and did knife tricks. Great success shooting the knife into the piano. The woodworms are so bad and eat hell out of all furniture that you can always claim the woodworms did it."
