Hi Phil,
Is this what the Champ/Indy cars run on?
I know one shouldn't laugh at such things, but it's a strange sight to see a pit lane fire with this stuff. The first clue is usually when one of the re-fuelling crew seems to initiate an impromptu performance of the River Dance, followed very shortly by his colleagues throwing buckets of water at him. So apart from the burning, there's the drowning and concussion to worry about.
