Not really too many cautions. At least, not as bad as years past that had 20 or something crazy like that.
When Jarrett and Newman tangoed for the second time, they showed the two crashes one after the other on the jumbotron. By the looks of it, it was quite deliberate.

Unfortunately, Kenseth led about 350 laps and ended up winning.
Who spun out in the last 15 laps or so? We had already left to go to the car at lap 480 and missed it.
Also, there were about 4 flybys by at least 2 squadrons (2 F-18s and 4 F-16s). Not sure what that was all about, but it was definately pretty cool.
