And this time, I did it the right way, so I got to run around in the park itself. See my Daily Mile post for details.
I took some pictures on the way:
The cows were out in force in the Walnut Creek Open Space (Acalanes Ridge)
This is heading up the hill in Briones, and I noticed that there was one brown cow.
The view from the top. I had to stop and admire it. I'm not sure my cameraphone does it justice.
Looking back the way I came, towards Mt. Diablo.
Another view from the top.
On the way back down, I got a much better view of the one brown cow.
