I appreciate all the help. On Monday morn, on the way back to Cotati, I'll stop in Schellville and poke around a bit more. My quick glimpses from the highway haven't been enough to tell the whole story.

I believe the rest of tale is told. The tracks from Petaluma north to Windsor look solid underneath all the grass, weeds, and other vegetation. Once it's all cleared away, we'll have a railroad again. Speaking of which, they look pretty solid up to Cloverdale and points north. This has to be good news, hm?
