Well in that case, the Mopar EuroNationals 2006.
It was the first proper event I have attended as a participant and not a spectator. From The moment I drove in till we started to pack up on sunday it was perminant silly grin time. I have wanted to be a part of the American Muscle scene since I was little and that was when I landed.
Will be giving this year a miss though (along with many other events and shows) due to arrival of mini me but will be back with avengence in 2008.
