Do contact lenses freeze? That was the first thing I thought as I checked the evening’s weather forecast. Why my first concern of spending a night in a hammock in a wood in subzero temperatures was my contact lenses rather than, say, my inadequate sleeping bag, I have no idea! It was New Year’s Eve when, after chatting to a friend about his outdoor plans for the new year, I had agreed to join him at the local bushcraft meet a few weeks later. Perhaps thanks to the festive ale I was consuming, I had also apparantly (my recollection is a little vague) agreed to leave my tent at home and borrow one of his hammocks. After last year’s 1000 mile challenge, I had decided that 2012 was going to be about experiencing the outdoors (rather than clocking up mileage) – so why not spend a night in a hammock in a wood?!
