From Steve from Seattle
I took a 4-hour photo car tour with Bob, who is a very patient, knowledgeable, and flexible guide.  He readily understood the scope of my interests and showed me all kinds of places off the beaten path that I never would have run into.  Plus he is a font of knowledge about architecture, local politics ...  Go with him.  You cannot do better.
