Not to be pickin' on TUFELHUNDEN, but there are so many photochopped signs in this thread ...
I in no way photo-shopped that picture. Seriously. I grew up in Red Bluff and knew that sign was there, I spent a lot of time on hwy 36 near where I took that picture. Took my first MSF course at 15 1/2 within 5 miles of that sign! I live in Southern California now, and on my return trip from Alaska last month I stopped by and took the shot. I'm sure there some Norcal natives here that can vouch for me. I DID NOT photoshop that picture. It is 100% real.
