What a list! I'd never really appreciated the enormity of John's FA contribution. Such genre defining classics as well.
I never met John, but his routes did give me what was probably (still) my best day of climbing. Back in February 2007. We spent the morning at Curbar where we did Canoe and got utterly spanked by The Toy. It was too hot! So we abandoned and headed to Burbage South for the afternoon where we did The Boggart, Boggart Left Hand, The Knock and Pebble Mill. What a great day that was!
