A couple weeks ago we had our first Majors race at the new Ozarks International Raceway. The 3.9 mile course has more elevation change per lap than any other track in the US and has everything from low speed to high speed corners. There's even a section of the track that is the longest straight line called the "roller coaster". Nineteen corners sounds like a lot but it was surprisingly easy to learn.
For those that want something different than their normal track they've been to 50 times, this should be on your list next year. It is a blast to drive and a bunch of people came away saying this was their new favorite track.
Here is a lap at speed, of course like most videos this doesn't do it justice, the elevation change is way more dramatic in person. Gearing was a wild guess and didn't feel like making any gearing changes during the weekend.
