Found this track as I was driving to Mount St. Helens in Toutle, Wa. 4 years ago. 1/8 outlaw track.

There was about 10 or 12 of us there that day. No return road. 2 or 3 pair go down the track, turn around and wait off to the right side until the starter waves a white flag. Then drive back to the starting line/ pit area. What a hoot.
