The kid with the memory was my son. 11 in a few weeks. He also climbed a fair bit down there. I think you met him on the belay on Conifer Ck during the Keyboard fiasco.
We did TTR together on Monday 30. Then Mantle with an old friend of ours. He enjoyed the balancy moves.
He has read the selected guide a fair bit. He is a fan of Glen & Simon's prose. definitely better for a 10 yo than reading trip epics or stories in Aussie Photographer. I'm glad he memorised the guide as it disappeared from our campsite on Thursday. It has my name and phone number in it and, not having as good a memory as the next generation, i'd like it back please.
