Our last major city was Regensburg, a maze of medieval alley ways, arches and plazas. It was snowing the day that we arrived. It warmed a little and turned to rain that night, which made the footing more treacherous and added weight to the snow on the roofs. They had a problem with roof avalanches (Dachlawine) while we were there. We just miss a avalanche that nailed a car in a alley.
