Keep in mind its $20 to get in and $15 for parking .. if your lucky $10 if you find it.. don't pay for parking if its $20.. there are cheaper around.. and bring a water bottle with you lots of long walking. You will get dehydrated and you I'm sure you won't want to buy a $5 water bottle after parking/entrance fees :P
Great show! lots of aftermarket ppl.. and lots of vendors too! Try to sit in all the expensive cars.. last year I sat in some nice $100K BMW's and Audis..
Though every year I have gone too I sat in Mercedes, BMW's, Audis and I even got to sit in a Viper!! but sit in a Focus SVT is totally off limits!
