The "Vinegar Valley Express" is/was a railbus, made by the McCloud River Railroad, that carried loggers to camps in the woods. I originally put up a page of photos taken at its "final resting place" east of McCloud in January 2000 here.
Recently I wanted to see how it looked after almost 12 years of weathering, but I had to walk in because the road was covered with a couple feet of snow.
This time I relied on a GPS unit rather than my feeble memory and found the car easily. The trees to the right of the car's front have grown curving along it's body.
Aside from a few missing floorboards the interior looks about the same as it did the last time I visited, including it's unique "dropped ceiling".
