The amazing thing to me is the fact the course was devoid of spectators. I saw few places with them, but tall fencing in front of them. Great video! When I was there many folks camped on the mountain the night before the race. It was really something. Looks like more than the road surface has changed.
I was going to camp it, until one of my buddies who lives in the springs told me the new spectator rules he heard about... No booze, no air horns, camping only allowed in certain designated areas, and the biggie you noticed... Spectators must stay behind the fences/barriers or in the woodline. Motorsports regulations are making all types of racing as bad as any other sport (with the exception of chasing your balls around a grassy field) they are now more fun to watch on TV, due to safety.
