Your piece brought back memories. In the 1970s there was a remarkable split-level howff in Coire Ardair where I once spent a squalid night with other members of Cambridge University MC, including Mike Geddes. We ran out of paraffin for the Primus while cooking the evening's curry, but discovered a tin of Cuprinol wood preservative, which burned pretty well. Upstairs, incredibly, were some foam mattresses. When I returned to Meggy a few years ago, the only signs of the howff were a few bits of broken timber.
