I've not been before, but am going this year. Hear that its an absolute blast, and the atmopshere is great: everyone is out there to have fun, and they are all Dub/Audi guys. Also, apparently, since there are only a few hotels out there, there is much debuchery on saturday night.
Admission is something like $8 is you buy online, and you can enter your car in a judged detailing comp for like $15. Everything I've heard and seen about it says good time kicking back with some car guys for a weekend.
Me and my buddy Scott [whos going on the rally this summer with me] will be going. hopefully in a cruse from somewhere over by baltimore/towson.
