You’re walking down a picturesque Riga street on a sunny winter day and all is right with the world when suddenly you hear a loud rumble from above. Mountain climbers would tell you not to look up, but they also have the luxury of helmets and you don’t. Not even the furry Russian shapka you bought at the market can save you from the colossal iceberg that’s about to land on your noggin. Each year a few unlucky souls are injured, some seriously, by falling ice and snow in the Latvian capital. Although all buildings are required to clear the white stuff from their roofs, some choose to risk a small fine instead of guaranteeing your safety, so keep an eye on the skies and be ready to run.
