For a number of us, Nationals also include the weekend prior when the ProSolo Finale is run and Nationals Warm Up practice start. So Nationals is then Sept 11-17.
It might be possible to blow of the earlier stuff and make it to LOG, but it would be nuts to drive to the east coast for LOG and then drive back to Kansas in one day.
Nationals- 1200 drivers in a multitude of classes. The best autocrossers in the US converge in Topeka to compete over a 4 day period. Support from various manufacturers like Toyota, Subaru, Dodge and tire companies Kumho and Hoosier.
For some of us, it is something we never miss.
