Today's hike was a straight 8 mile out-and-back along the paved Nimitz Way; starting at 10am and hoping to avoid the threatened rainstorms forming off the coast. And it worked: not only did the rain hold off, but it was clear enough to get some good views over San Francisco.
(I'm still at the stage where a view of the Golden Gate Bridge is a novelty; and there are plenty of great views around, including one downhill stretch of Highway 24, just after the Caldecott Tunnel, which has near-panoramic views over Oakland, Emeryville and Berkeley, and across the Bay to the city. Not the sort of view you used to get from the M4...)
Anyway, it was a lot of fun to walk and chat; I'm hoping to get out with them again next time they hike.
