I like the one of Blacks Bridge/Eureka, in high school we camped there every weekend under an old apple tree. I knew someone who said his father was one of the original members. Supposedly he had old pictures of model Ts parked out there and he said he also had one with a small plane that landed out there too. I cant see but your newest picture looks like the wood bridge that I remember from the 80s, I am not sure when they installed the metal bridge
