I went to this back in the MKV R32 with mine, at the time it was an amazing event. And at that time it was like 90% R32's there. That made it really fun because with the exception of a few boosted R's all the cars could keep up with one another, sounded awesome (did a sound off) and took lots of cool pictures. The weekend I was there some jackass from another group ran a motorcycle off the road, and I believe someone else crashed on the dragon, it is almost expected there will be an accident.
Great event when it started, I'm sure it is still good, but seems to have been greatly diluted with all kinds of different cars coming and that leads to people attempting to show off their so called driving skills and why their car is better.
