I've got that Ski Mountaineering in Scotland book. Never realised how valuable it was, and have only actually used it once. In a week when there was so much snow they closed the Lecht ski resort, but that is a tale for another time.
I'm willing to sell this valuable book to any interested parties for 20% less than it's on offer in Amazon. Be assured that the money will be put to good use: funding a 3 week trip to Canmore.
