I'm not much of a Formula 1 fan (although I followed it more or less regularly at times) but I once was at the track when they had a training session and I had goosebumps.

You hear it kilometers away from the track and once you're there you are totally engrossed by the sounds of the machines - basically vibrating through your body. I'm having trouble to describe it (maybe someone else can do it) but it's definitely a total different experience than watching on TV and I recommend it to anyone to hear for yourself just once.
