It's March and I find the enthusiasm to venture out again. There are signs that the winter - the coldest for 30 years - is coming to an end. The field next to the track down to the cliffs is newly ploughed. Acid yellow gorse stands out against the grey of the sky, the rich dark brown of the soil and the washed out colours of dead grasses.
A group of people and a dog are clustered around a man giving a talk. One of them, Nick Taylor, explains that the listeners are from Duchy College on the outskirts of Camborne and are listening to a representative of the National Trust explain the Trust's policy for management of this area which is a site of special scientific interest. I want to ask if I can stay to listen and learn more, but don't have the nerve. So I walk on.
