In the train, riding to San Francisco. I notice every other passenger is dressed in bright orange garb. There must be a Giants game. I can feel the excitement grow as we get closer to the city. The herd mentality in full display. How to tap into this urge people have to belong? What are some eco-heroes they could get excited about? There is Al Gore, of course. Nah! What we need are charismatic personalities who can ignite the crowds. Any ideas?
