Spike, as I said above, I haven't had time to follow NASCAR this season, and this week I just checked out a couple clips of Sunday's race. It led me to wonder what you thought of the Charlotte Road Course.
Oval racing isn't that big over here, so I'm used to watching pretty much all track-based motor racing on what you'd call road courses (F1 courses are generally just known as tracks/circuits, with the exception of street circuits which used closed-off streets). When F1 was briefly at Indianapolis (2000-2007), they used an infield course in conjunction with about a mile of the oval (run in reverse). Rockingham is the only speedway in the UK (there are apparently only two in Europe), and the only racing series that I follow that uses Rockingham is British Touring Cars (BTCC), and they use its road course.
