Not sure if any of you guys go to this but you should. I go every year and get a hotel its so much fun! It starts the 1st and goes till the 3rd this weekend.
They have a massive car show (they say over 5000 cars), burnout competitions, 1/8th mile drag racing in the city, bikini contest, flamethrower competition, deisel smoke contest, beer tents, live rock n' roll, a drive in movie, stunt bikes, and lots more stuff.
I always have a blast and like I said I'll be there all weekend. Post up if your planning on going.
Heres the website with lots of info and pics from other years.
