Al Gore recently gave a speech where the advertisements encouraged people to ride their bikes (in 90 degree heat) or take public transportation to get to the event.
Gore, always looking to live out his do as I say not as I do philosophy on life, showed up with a fleet of cars and SUV's.
This video is taken by a group who crashed the event and asked some attendees why they didn't ride their bikes, and they ask Gore's driver why he's leaving the car idling with the air conditioning on!
