Things to do in Zurich
Lenin: "On Thursday afternoons when the library was closed, we climbed the Zurichberg. Coming home from the library Ilyich would buy two bars of nut chocolate in blue wrappers at 15 centimes, and after lunch we took the chocolate and some books and went off to the mountain. We had our favourite spot there in the heart of the woods, where there were no people about, and Ilyich would lie in the grass deep in his reading."
