This is rather random and only for the ambitious or those with time on their hands - I'm not sure I'll like the results any better than what's been done so far, which is great. The coordinates shown are for a famous section of race track at Mazda Raceway Leguna Seca in California - 36°35'05.45"N, 121°44'56.35"W - enter in Google Earth or other mapping program with a satellite view, and turn the image around so you are facing West (North is on your right hand). Also here but less useful -
http://www.mazdaraceway.com/pages/Track_Map - look for the "Corkscrew." To get an idea, going from left to right (actually it's from South to North) you go up a long hill into a tight left turn, at which time the elevation begins to drop as you make another quick right turn and finally into a sweeping left hand turn at which time you've dropped about 100'. I know it would be especially hard to portray the elevation drops in a 2D logo, but if possible to express that would add a lot of impact and realism. So I'm thinking someone may be able to do something with the lines around the text that (or otherwise in artwork) that reflect this section of track.
