30 years ago I read this book , the 1981 Epic of New Zealander's  Peter Hillary (Sir Ed's son) and Graeme Dingle as they made the first ever traverse of the Himalayas. there journey ended on the Baltoro glacier at Concordia  right below K2 and Broad Peak. Ever since seeing the photos of Concordia and its surrounds all those years ago there rested in my mind the idea of going there. The vision has expanded - little would've I have imagined back than the idea of trying to climb one of the giants yet alone taking a bicycle up there!!
