Somewhere recently I heard there were 16 (or was it 18?) covered bridges in California. I've been to the Bridgeport one, west of Grass Valley, which by the way is the longest single-span covered bridge in the country. I'd also heard about one in Knights Ferry, and finally got around to looking for (and finding) it a couple weeks ago.
I also found some old building ruins next to the bridge. I wasn't expecting that. This is what is left of an old mill:
This being "Gold Country", I assumed it was a stamp mill, but I found some signs near it that said it was the remains of a flour mill.
One more shot of the mill ruins and foundation. You can see the bridge in the background, behind the trees:
