In reply to Iain Thow:
RIP indeed. A true enthusiast.
I think Big Walks is, in its own way, probably the most inspirational of the whole series. Of course he wrote and edited many other books, including others in the series, but the Big Walks is a really special and coherent collection and a fabulous book. And every bit as challenging to complete as most of the others (collapsed rock routes notwithstanding)!
