If you can't figure it out from the names, these are some of Germany's nicest road courses. Pretty much all North American tracks pale in comparison.
That huge one is the Nurburgring Nordschleife. It is 24.4Kms long, inside it are separate 10Km and 5Km road courses. A very very fast lap around the Nordschleife is about 7:40! Can you imagine an 8 minute road course?!
