Saturday I was at the newly opened Oregon Raceway Park. The track is more construction zone than finished product. The in-field is dirt, the last 3 miles of road leading to the track is dirt, there's no power, no water. In the afternoon when the wind and dust kicked up the visibility dropped to zero. A few sessions were cut short and I called it a day around 2pm.
But the track surface itself was in place. And early in the day the weather was nearly perfect. Here's a video of one of the early laps:
It definitely has some interesting sections. Lots of blind areas where you have to remember where the track went last lap and hope it hasn't moved since. Once they sort out dirt control (grass in-field, added curbing) it should be a great track.
