Brian,
WOW! It's right there!
I spent many-a-summer's of my childhood with relatives in Colusa. It would be many years later before I learned of the Coulsa and Lake.
Now I know I've seen it, ridden in a car past there hundreds of times, I just didn't have a clue as to what it was. I doubt I'll make it back up there before it's gone.
California is quickly losing it's historical places. Thank God there's places like Sumpter, Chama, Orbisonia & Alna where people know how delicate heritage can be.
Thanks again,
Curtis F.
