Andy Kirkpatrick's tricks for mountaineering kickstarter
Posting this because it's been flying quite under the radar, but guy's got 30 years of the sort of experience not many people have (first ascents in Antarctica etc). and is now writing a stuff-i-learned book. I've found his previous "Down" an invaluable how-to in how to safely descend stuff so I have high hopes for this one too, and I'm putting it here in case anyone else missed it
