i went as well, finished 11th of 12 in 'open C' got my butt kicked. both races i had a bad start, in the main i stalled it at the gate(long story short, the clutch started to grab just before the gate dropped so i hit the brake instead of the gate) got out just as everyone was rounding the 1st corner... made up all but 50 ft on the next rider.
what an experience, the track was killer, & the pros were nothing short of awesome to watch. 460+ riders attended.
i went to glamis for a couple days after & just got back last night.
if the nationals come back next year, i'm not sure if i'll go, but if i do, i plan to be on a different bike... something i can run in production or 4-stroke classes.... where there are less sandbaggers.
