Julius, if there is any way for you to go to a national GO. the difference between a National and Supercross is night and day. SX is all about the show and commercialism wheras a National is about racing.
The riders are very accessible both in the pits and out walking the track. Thekid and I spent quite a bit of time talking with different riders (Brown, Huffman, Vuillemin, Ferry, Langston, Hofmaster, and quirte a few others). This was not the hi can you sign this but discussoins about them and their bikes. Last year at Troy thekid was on crutches from a crash 3 days before and Travis Pastrana actually sat down in the infield and talked to him about riding and injuries for 10 minutes. The memories of meeting these guys for him makes the trips worth it.
If you can get up here next year we will see to it that you do Millville the way it should be done
