View from somewhere on Page Mill Road, en route to Portola Redwoods State Park, late June or early July:

The difference in temperature between the valley floor, where all the city is (Los Altos and such), and the tops of these ridges is quite startling. This was quite late in the morning, and as you can see there was still fog in some places; up here it was an average of 15 degrees cooler than down below, in some places as much as 20 degrees. (55-60 vs. about 75). Rather pleasant, really, despite the crazy locals driving on the shoulderless, two-lanes-in-name-only, blind-curve-having, bumpity, pothole-ridden road at about 40 mph (where a top speed of 25 is all I recommend and in many spots you really can't safely go much faster than 15). Is there no road in this part of California so remote it's devoid of crazy locals? Bah.
