To train my skills I went climbing in bad weather last winter, knowing it would get really bad by forecast. Had to flee out of that area due to avalanche risks at night in a bad snowstorm. All intended... But I got to know my new GPS very well in that moment. Finally came to a road (Julierpass) in the morning just after dawn for hitchhike. The snowplough-drivers gave me some big questioned looks. Since, I trust in that small device.
My girlfriend suffers throughout winter, actually last night she already started a 4 month suffering, due to my cool room. No heating - no cheating.
I will leave my sleeping bag at home, just to test my down clothing. This can bring me to smashing a window from a snowed in alp-hut, then spending a cold night trying to make a fire in the fireplace. Recently I tested some solar panells in town, in the streets and got some weird looks. Luckily I was wearing sunglasses.
