      Responding to Mike Harrington,

      I'm going to have to drop this discussion due to the press of time.

      To be clear, I'm not an economist of any stripe, and most certainly
      not a supply-sider. Maybe $10/gallon fuel from renewable sources
      will be there, maybe not. All I'm saying is that we should not base
      our strategy for implementing carfree cities on the availability,
      or not, of energy, at whatever price. These are not the most important
      reasons for moving to carfere cities. I think that we should sell
      the idea on all its merits, without claiming that carfree cities must
      inevitably come about just because the oil is running out.
