The most technical track in the world. American car companies are starting to test cars there now. This past summer, the puget sound BMW CCA chapter went to the ring for a week. One day there was a motorcycle fatality. Apparently, fatalities are quite common on the track when you have average people with cars they can't possible handle on that track. It is 14 miles long, tons of curves, elevation changes, off camber. Way difficult to drive fast. I would love to go and take some laps.
