Lafayette is a wealthy town in Contra Costa County, which is inland from Berkeley and Oakland. There is a public park with a nice 3-mile walk around it (paved). We went out this afternoon and did it. It was quite crowded as it is the first sunny weekend in a while (according to my parents). I saw an osprey flying off the water with a small fish in tow. Northern California outdoors is quite beautiful and I hope to take advantage of it while I am here.
