By the way, I also checked some more of the photos I shot at Silver State. Guess what, the CEN sticker is also upside down. And the link in the first post is wrong, my opps, it should be:

RC Cars, Buggies and Trucks >> RC Regional Racers >> 2006 Las Vegas RC Tracks & Events

Silver State photos start around page 12.
