dminor,
Are those pictures from the infamous Desert 100 that used to be held in Mattawa?

If it is, I have raced that race several times, but in different locations. Closer to Vantage, and now Odessa.


They still do the old-school desert start of a "bomb run", with up to 1,800 bikes on the starting line. It stretches for over a mile long! I think I got 18th overall back around 2002.
