Well, I gave it a ten because:
1. The weather was epic
2. The race itself was really good
3. It's a humungous event and the atmosphere was amazing
4. I got to stand at the start of the entry to pit lane with the cars entering at full racing speed, changing *up* as they passed at something like 150mph only 6 feet away from me.
As an aside, of all the cars this weekend it was the Ferraris that felt like they created the biggest 'hole in the air'. Each time they pitted they made the legs on my overalls flap
