Has Anyone Gone To VIR?S

I would like to plan a trip down there (from MD) with a friend to see the Tudor USCC in August. Since I still live a considerable distance away and am in college I would camp there. Has anyone done this? Also, is it worth staying for the three days, or should I just go for the major race? Are there any other things I need to know before going? I'm clueless and just want to see a SRT GTS-R scream around a track.
