In reply to zmv:
yep, saw Tommy at the RGS earlier this year and got a signed copy of The Push.
This has led us on to Alex Honolds book Alone on the Wall and so it goes on!
I like the look of Yoemite by Huber and Zak so will give that a go.
Many thanks for everyones recommendations, If anyone is planning a trip out west in the next few years and needs a keen bag boy, let me know!
