A change in weather: July 21

I learned two things today during our hike on Montara Mountain at San Pedro Valley County Park in Pacifica. First, you don't have to go far outside the city to go hiking, and second, the weather can change dramatically in a couple of hours. It was overcast when we started, and as we moved up into the hills from the trailhead, the fog became so thick we lost sight of the coast and even the neighboring hilltops. By the time we descended, the temperature had warmed 10 degrees.
