It is appalling that the very country that the North Atlantic Treaty Organization (that is, the new and improved all-inclusive NATO) regards as an international leader in cyber defense, according to Mike Collier's article in the February issue of City Paper, still sows a thin string of sand on its sidewalks as well as on the platforms of its train stations to keep people from slipping on the ice and snow. It is scandalous that the country that is, according to Collier, "committed to developing a cutting-edge cyber-security industry [and selling] its expertise around the globe" doesn't know what the hell road salt is.
They do still use road salt in some places, most notably hilly bits of road and busy intersections (the former being rare in Estonia, the latter increasingly less so), but not for sidewalks and train platforms and level roads, for a very good reason: salt fucks things up. It's incredibly bad for cars, because it goes right through the paintjob and causes corrosion; and it's incredibly bad for your shoes. Moving about on foot in Estonia in the winter is a trick you can learn, and locals inevitably do - it helps to have shoes with interesting tread patterns on the soles - but ubiquitous salt usage is something that was done in the Soviet days, and mercifully is not done any more.
Then again, mr. Hogan there lives in Tapa - presumably of his own free will - so without knowing more, I am not entirely confident in his judgement. [grin, duck, run]
