I had seats at the start-finish line at the '06 USGP.

It was fucking amazing when each car started up its engine in its garage, pulled up to the end of the pit lane, hit the launch control (this was when they still had it) and rocketed down the front straight. Holy crap. All that beautiful noise echoing through the grandstands. I was totally not prepared for the awesomeness.

I didn't bring ear plugs. I was fine for most of the race but towards the end I kind of wanted em. If/when I make it back to another F1 race I'll probably bring ear plugs but try to hold off from using them for as long as possible.
