I love walking and it’s probably the most important activity in my life, apart from painting. Even during the worst weather I chuck myself out of the door and force myself up that hill and along the cliff path. Snow is beautiful, it can’t be denied, and walking in it can feel like I have entered a parallel universe. But when it’s accompanied by Siberian ice-wind it’s a different matter. Getting a teenage boy to go for a long walk in the snow is no mean feat, but bribery works.
