Ice on the sidewalk isn’t the only hazard that pedestrians face in the winter. Long, sharp icicles looming overhead pose another threat. Last Saturday, while walking down Universiteto street in Vilnius, I observed a large chunk of snow come crashing down from the roof of a building. Fortunately no one was standing in that particular spot at that particular moment. As long as the temperature stays below freezing, we are mostly safe. But once it starts to warm up, be careful of snow and ice overhead!
