I took these photos last Summer while we drove through the one-way tunnel that is the entrance into the Marin Headlands of Northern California, a part of the Golden Gate National Recreation Area. I can’t remember how long the tunnel was, but it was a long one — I mean, there is a sign that instructed drivers to turn off their auto engines while waiting in line, if that says anything… Luckily, I’m not claustrophobic and driving through tunnels don’t bother me. It was actually a fun drive and a good photo opportunity.
