You know, I've crashed at both those tracks, Daytona also, then there was Savanah...
AnywayI've done both drag racing and road racing, IMO the difference is that in drag racing the intensity is wadded up into a 10 second blast, any screw up, miscue or wahtever bites you in the azz instantly, road racing on the other hand is jsut as intense, it's just spread out over more laps. Really, I've always felt a racedriver could drive anything, it's in the genes.
The bad thing about the drags is that they don't last long enough, the good thing is, they're a lot easier on the body work. Road racing is just the opposite, it lasts longer but is harder on the sheetmetal. As for drivelines, they all break sooner or later. The key is to find either drag racing or road racing that you can be competitive with on a specific budget. If you don't get all goo goo over the exotic stuff you can find it in both venues.
