An interesting note on Global warming, the "Top Gear" boys recently drove several pickups to the magnetic north pole to prove that Al Gore's statment that "the pack ice over the north pole was all gone" was an inconvinent lie, As one of the presenters commented, "How hard can it be if two fat, mostly drunk blokes can drive to the north pole?" he later admited that it was actually pretty hard.
Best wishes
