We rarely get snow here, and when we do it doesn't last, so we have no tradition of householders shovelling snow. By the time we all realised we should have done something it was too late, and the pavements were appalling. About a month ago I had decided to walk to my osteopath's appointment (a mile away), discovered after 5 minutes that it was impossible and went back for the car. Yaktrax would definitely have helped!
