Our writer and friend Robert Macfarlane referred to our other friend and writer Alastair Humprheys as “the amazing ball of adventure-energy that is Al Humphreys.” Indeed. But Mr. Humphreys is not a perpetual-motion machine. Like all of us, he sometimes suffers from the digital hangover and the perma-connected blues, and when that happens he bails to the Scottish mountain huts knowns as bothies. As boltholes, there are few things better.
